Re: Thermal printer small "bracket" use??? Message #5 Posted by David Smith on 23 Mar 2002, 5:52 p.m., in response to message #4 by John K. (US)
I have purchased several of the 82143A printers on Ebay for under $25... some under $5. Most were listed as in unknown or broken condition, all wound up working... some after a little repair.
Most common problems are:
1) Dirty mechanisms (needs cleaning and oiling). Four screws are under the rubber feet. One in a hole near the center of the calulator. The printer mechanism is held in by three screws. If you overtighten the one by the motor, the head will lock up. The printer screw bosses are often times cracked. Same for the screw boss for the case corner screw by the security cable mount.
2) Bad drive belt (head wont move and printer locks up). A 2.3-2.4 inch circumference belt around 0.048 thick. Most o-rings are too fat. Projector Recorder Belt Company SCX2.4 works well.
3) Bad (or missing) battery or charger. These are almost always available on Ebay. Old battery packs can be rebuilt for under $25. Printer will not work on AC alone. It needs a somewhat good battery.
4) Missing paper tear bar. Still works without it but it is annoying. You can fake one out of some thin clear plastic.
5) Bad dot(s) in the print head... you are out of luck.
