- • WordWorks problems − In reply to Dave Floyd’s WordWorks problems
- (Archive 7.8 p43) one of our subscribers (I didn’t catch the name,
- sorry) called in with a solution that works for him. Once you have
- deleted the choices file and got the configurations back as you want
- them, quit WordWorks and then load the choices file into Edit. Find the
- line that starts NewView followed by some coordinates and comment it out
- by placing a colon at the start of the line. Save the file back and all
- should be well. Dave Webb, NCS.

- • CC Turbo drivers − It has been stated in the past that to print from
- Basic (or similar), you need to load the Turbo Driver before it will
- work. This is not, in fact, the case. After installation, the !Printers
- directory will contain a directory called td, which is where the Turbo
- Driver resources are kept. In the subdirectory Resources.Modules is a
- relocatable module ‘turbo’ which is all that is required to enable
- printing from Basic. If you frequently wish to print in this way, it may
- be beneficial to load the module as part of your boot sequence. G.
- Smith, London.

- • Conditional Basic − Following hours of head-scratching and computer-
- bashing, wondering why an “IF...THEN...ELSE...ENDIF” did not work as it
- should, I made the following discovery. The problem occurs if you are
- using !StrongEd when after the THEN, for whatever reason, there is a
- space which you cannot see. (It is possible to make it visible in
- !StrongEd since you can set the window and text background colours
- independently, e.g. two different shades of grey. MH) In my case, it was
- left there after splitting the line. The program then seems to ignore
- the THEN and just continues its flow, and of course, if the condition
- has not been satisfied, the wrong result is achieved. If you delete the
- unseen space or spaces it works correctly. The same does not occur with
- !Edit. How about other editors? John Charman, Norfolk.
- 7.8
- (I have tried this with the public domain editor, !Zap. If you edit in
- BASTXT mode, the spaces are saved, but the program functions correctly.
- If you edit in Basic mode, trailing spaces are removed. Is there a
- difference if you run the program from within !StrongEd, rather than
- saving the file and running it normally? MH)

- • Deskjet printing − Examining the printer graphics output for the
- Deskjet from the Acorn Printer driver, I see that graphics output ends
- with the code <esc>*rB. This was the accepted code until the DJ500 but,
- thereafter, <esc>*rC is required. The latter is recommended to cover
- both cases. In the !Paint code, it is immediately followed by <esc>E to
- reinitialise the printer, so it would probably work OK but, in other
- contexts, it could have undefined results. John Laski, London SW1.

- • Epson Stylus and Turbo Driver − If you are having problems with
- spurious formfeeds being sent out to the Epson Stylus printer from the
- CC Turbo Driver, don’t despair. It is a known problem and Computer
- Concepts have a fixed version of the Turbo Driver. Contact them for more
- details. Michael Pullin, Cheltenham.

- • Ink Refills for Canon BJC-600 − The Canon Inkjet Colour Printer BJC-
- 600 is highly regarded as a suitable colour printer for Acorn 32-bit
- (Archimedes) computers. It produces prints with 360 dpi resolution and
- near-photographic quality in colour of an excellence previously
- obtainable only with much more expensive printers. The method of
- printing is to eject coloured inks in very small droplets from separate
- reservoirs of ink of four colours (yellow, cyan, magenta and black)
- through holes of microscopic size in a print-head which is traversed
- laterally as the paper is advanced beneath it.
- 7.8
- In the Canon BJC-600, the print-head is retained in the machine and only
- requires renewal at long intervals. The four inks are contained in
- liquid form in separate plastic cartridges which are conveniently
- transparent to show the quantity of ink remaining. These four cartridges
- plug into the print head and can be removed and replaced individually.
- Each cartridge is sealed except for one hole which feeds ink to the
- print head (the ink exit hole). A spongy material which is located
- within the cartridge absorbs some of the ink and prevents it flowing too
- freely from the cartridge.
- 7.8
- Ink refill kits have become available to save on the cost of new
- cartridges. It is particularly important, if refilling is contemplated,
- that only inks of the special types used in inkjet printers should be
- employed.
- 7.8
- In my experience, it is not satisfactory to attempt to inject new ink
- through the ink exit hole: Filling in that fashion can only be done
- slowly as air must exit at the same time by the same hole. Furthermore,
- there is a risk of disturbing the spongy material within the cartridge
- at the critical position in the vicinity of the hole. So, my solution
- has been to drill another hole in the cartridge for filling with ink.
- Although this and the subsequent operations which I shall describe are
- simple in nature, they require some dexterity. If you wish to experiment
- at your own risk, proceed as follows:
- 7.8
- To modify the cartridge, peel back the coloured adhesive label to expose
- the top of the cartridge. Drill a small hole in the centre of the round
- moulding depression on the top of the cartridge (see diagram opposite).
- I shall call this the filling hole.
- 7.8
- Take a piece of adhesive tape of about ¾“ square − the common brown
- adhesive packaging tape is ideal as it adheres strongly to the material
- of the cartridge. Place this tape to cover the filling hole which you
- have drilled and bend the tape to extend it over the side of the
- cartridge. This extension will facilitate its removal later. Finally,
- smooth back the coloured label to its normal position at the top of the
- cartridge. This completes the modification of the cartridge.
- 7.8
- Filling a modified cartridge.
- 7.8
- (a) My experience in refilling cartridges is limited to the use of ink
- obtained from System Insight of Welwyn Garden City which I have found to
- be satisfactory. The ink is supplied in plastic squeeze bottles which
- are very convenient − specify that ink is required for the BJC-600 and
- the bottles will be fitted with long straight hollow needles (or probes)
- somewhat like a hypodermic syringe. Ink of all four colours will be
- required.
- 7.8
- (b) Seal off temporarily the ink exit hole in the cartridge with tape.
- This requires care as the exit hole is near a corner of the cartridge. A
- clamp against a soft rubber washer as a seal is a better solution.
- 7.8
- (c) Peel back the coloured label at the top of an empty cartridge to
- expose the brown tape and remove this brown tape to expose the filling
- hole. Insert the probe of a squeeze bottle containing ink of the correct
- colour (check the colour of the cartridge label carefully) and fill the
- cartridge with ink. Do not overfill but move the cartridge as necessary
- to ensure that air is not trapped.
- 7.8
- (d) Seal the filling hole again with a fresh piece of brown adhesive
- tape. Smooth back the coloured label over the top of the cartridge.
- Remove the tape (or other seal) which was placed temporarily over the
- ink exit hole.
- 7.8
- (e) Place the cartridges vertically on a flat surface (in the stance
- they would normally occupy when in the printer) and leave them overnight
- to stabilize. There should be no leakage.
- 7.8
- (f) Place the newly filled cartridges in the printer and perform the
- four-colour cleaning operation which would normally be carried out with
- new cartridges.
- 7.8
- You should note that you will be unlikely to complete these filling
- operations without spilling some ink especially until experience is
- gained. So take care to undertake filling where spilled ink is of no
- consequence. Toilet tissue is the best material for mopping up surplus
- ink. A small quantity of ink on the hands is of little consequence as it
- soon disappears with normal washing.
- 7.8
- The amount of money to be saved by refilling cartridges is worth the
- effort if the printer is used extensively. On the other hand, success
- will depend considerably on your manipulative skill − you may consider
- it preferable to employ only new cartridges as supplied by Canon.

- • Laser Direct and RISC OS 3 − Having recently upgraded to the RISC OS
- 3 version of the Laser Direct printer driver (v2.61), I’ve hit a couple
- of snags when using a Canon LBP-4 printer fitted with a paper cassette.
- Thinking these were new bugs, I reported them to Computer Concepts but
- have been advised that they are ‘features’ of the (RISC OS 3) model.
- 7.8
- In neither case do the problems stop successful printing but they do
- need to be taken into account, thus making the system not quite so user-
- friendly.
- 7.8
- When the driver is first loaded and the paper cassette is selected, the
- printer Alarm LED now remains on and the Status window shows ‘No paper
- in multi-purpose tray’. This is not normally a problem as, once the
- first page of a document has been assembled, the Ready LED comes on and
- the printer fires up (thereafter, the Ready LED remains on). However,
- where an application allows individual pages to be selected, e.g.
- Pipedream’s ‘Wait between pages’ option, the printer may not fire up
- until the final page of the document has been accepted or rejected. With
- a large document, many minutes can be lost.
- 7.8
- There are two work-around solutions; put a sheet of paper in the multi-
- purpose tray or first print another full document. Either action will
- bring on the Ready LED and allow printing to start as soon as the first
- selected page has been assembled.
- 7.8
- Secondly, when you use the ‘Print to file’ option, the paper feed
- selected at the time is now saved with the file and, on printing, will
- override any other setting. So, when printing to file, you must decide
- where you want the paper to come from when the file is finally printed,
- and pre-select Cassette or Multi-Purpose before printing to file. Jim
- Nottingham, York.

- • PipeDream to Impression − In Archive 7.7 p56, Paul mentioned getting
- files from Pipedream to Impression via DeskEdit. If you have PipeDream4,
- there is an option “Paragraph” on the save window. If you click that,
- you can drop the text straight from PipeDream into Impression. Michael
- Wright, Teignmouth.

- • Quieter fans? − David Lenthall (Archive 7.6 p23) asked for a supply
- of quiet Papst fans. You could try a company called Papst Direct,
- Andover, Hants, SP10 3RT (0264-335714) (0264-332182) who advertised in
- Computer Shopper some while back. Their Variofan will “run as fast as
- your PC needs”. I haven’t tried them myself so if anyone does, perhaps
- they would report back so we can all benefit. Thanks. David White,
- Cambridge.

- • Rodent sunglasses? − As a person of the bearded persuasion (those who
- met Dave at Acorn World or the NCS Open Day can confirm that!) who
- sometimes eats digestive biscuits whilst working at my Archimedes, my
- keyboard and mouse mat often suffer a shower of crumbs and small hairs
- as I scratch my chin. This requires frequent removal and cleaning of the
- rubber ball in the mouse.
- 7.8
- I have become accustomed to this so the other day, when the mouse
- pointer started moving in jerks I removed the ball and cleaned it. No
- improvement. I tried again, this time cleaning the little rollers with a
- cotton bud as well. Still it wouldn’t work properly. I washed the mouse
- mat but again, it misbehaved.
- 7.8
- The mouse I normally use was actually taken from an A3020 because I
- prefer it to the one supplied with my A5000, so at this point, I decided
- to try the original mouse and everything worked perfectly.
- 7.8
- A little later, determined not to be beaten, I took the top off the
- mouse to give it a thorough clean. This still produced no improvement. I
- therefore tried using it with the top cover removed in the hope of being
- able to see what was going wrong. All the little rollers appeared to be
- turning, but the mouse pointer wasn’t moving, just vibrating as I moved
- the mouse.
- 7.8
- The mouse uses an optical sensor with a slotted disc and, with the top
- removed, there was too much light for this to function whereas shielding
- the works with my hand made it function correctly.
- 7.8
- Suddenly the penny dropped! I refitted the cover, placed my hand
- completely over the mouse (instead of just moving it held between thumb
- and little finger as usual) and it worked. The trouble was that I work
- with my desk in a bay window, and it was the first sunny day of the
- year. The afternoon sun shining through the window was landing on my
- desk just where I had positioned the mouse mat. Enough of this bright
- sunlight was penetrating the casing of the mouse to confuse the optical
- sensor. I had wasted about an hour trying to find a non-existent fault
- when all that was needed was to partially draw the curtains!
- 7.8
- I have now stuck some kitchen foil to the inside of my mouse casing!

- • !Spark(plug) 2.22 − John Laski also writes of !Spark “this
- successfully unzips some files, but not others.” Unfortunately there
- have been later versions of ZIP on the PC than !Spark will currently
- handle. If you have access to the PC Emulator, I would recommend that
- you use the PKUNZIP program within the PC partition. While slower than
- !Spark, it does have the advantage that the decompressed files have the
- correct extensions (which !Spark does not (yet?) offer), and if the
- software is PC anyway, extracting it via !Spark to the PC partition and
- then having to rename all the files is more hassle than resorting to
- DOS. If you are sending the files to a Pocket Book (much of the Psion 3
- software is distributed through PC media) then with PocketFS2 you can
- drag a file directly from the PC partition to the PocketFS filer (not
- the translation window), which is another advantage of the PC method.
- Hopefully, future versions of !Spark will support extensions, as well as
- later versions of ZIP files, thus making my PC partition redundant!

- • Taxan 789 problems − I’ve been offered quite a bit of advice on my
- Taxan 789 problem; unfortunately, none of it is definitive and some of
- it is contradictory. However, the general consensus is that the Taxan
- 789 should run OK direct from ‘new’ machines, i.e. A5000 or later. It
- may run off ‘old’ machines, with or without multisync VIDC enhancers,
- but this is unlikely. It probably will run OK with SVGA VIDC enhancers,
- such as the version marketed by Watford Electronics.
- 7.8
- Apparently, the clue is whether the computer/VIDC enhancer produces a
- composite sync or the preferred separate horizontal and vertical syncs.
- This may explain why I had identical problems trying to run it from an
- A410/1, with multisync enhancer, or an A540 with built-in equivalent
- hardware.
- 7.8
- I’m now running the monitor successfully from a State Machine G16 card
- and am extremely impressed with the display quality in the higher-
- resolution modes, which is only marginally down on that of my Eizo
- F550i. While I agree entirely with Stuart Bell’s rationale on 14“ versus
- 17” monitors (Archive 7.4 p31), for someone who cannot justify the
- expense of the latter, a 14“ monitor and colour card (and, in my case, a
- pair of reading glasses...) would make a relatively economical
- compromise. Jim Nottingham, York. A
