Re: Converting 2225 A,C or D to 2225B ?? Message #2 Posted by Tony Duell (UK) on 29 Sept 2002, 2:07 p.m., in response to message #1 by Steve Seto
The first thing to be aware of is that because the 2225B (and for that matter the 2225P) are battery-powered, they use different (lower voltage) stepper motors to the A, C, or D models. So you can't swap the entire mechanism between a -B and anything else.
The mechanical parts (gears, carriage, tapewire, etc) are the same on all Thinkjets. You could use such parts from any model to repair a -B. The stepper motors are held to the mechanism by obvious screws, so it's easy to swap them over to put the lower voltage ones on the mechanism that ends up in the -B.
The 2225A (HPIB), but not the -C or -D does have a sort-of HPIL interface internally between the HPIB board at the back and the rest of the printer. It would be possible to rescue the HPIL pulse transformer, connector, and associated components from a -B and make a little interface to fit in place of the HPIB board. THis would give you a mains-powered HPIL printer -- not strictly a -B.
What's the problem with your -B? With more information I can probably tell you what parts you can rescue from where.
