Can anyone help me with procedure for changing developer on Mita DC 1255.
as dev. unit is sitting in machine, toner hopper is on right side. pull dev. unit out and remove toner hopper by removing two screws. dump old dev and replace with new. re-install toner hopper. install dev. unit. cheat the safety switch so you can run machine with door open. turn on power while holding "stop/clear" and "print" keys at same time. within two seconds, press "stop/clear". you should see U00. go to U60 and press "print". let it run for 4-5 minutes and then adjust potentiometer on front of dev. unit to where the three middle leds in copy exposure stays steady. make sure copier is level b4 doing all of this. when done, press "stop/clear" key and remove your safety switch cheater. that should do it. good luck!

Some minor points.
When you dump out the old developer, you should vacuum out the developer unit as completely as possible and clean the residual developer off of the developing roller to avoid contaminating the new developer!
On the sim modes; you won't see a "U", but just "00", "60", or whatever sim you select.
You only need to run it for three minutes prior to adjusting the pot in order to correctly "set" the new developer!
Other than that, everything is good-to-go!
good points kj as i was going by memory. i forgot the 1255 shuts off after three min. unlike the 1205.

I figured that was the case! Fortunately (or otherwise) I still have several of those in the field, so my memory is fairly fresh; I just did one a couple of weeks ago! I sold a lot of them several times over; I sold them when new, and some I've now got going through their forth trade-in/resale!
I liked that model quite a lot!

Thanks Ray! Same goes! Sounds like we travel "the same path" in business, and you're only about 435 mile from me by highway; I'm in the U.P. about an hour NE of the MI/WI border on the Green Bay/Menominee River.
you're right. they were/are a very good machine, however, i don't have but a couple in the field. i have ten times as many 1205's and 1400's which are also very good models. nice chatting with you. if you think i can ever help you, e-mail me at firstname.lastname@example.org. i work mainly on mitas and copystars, low to mid-range models, but i also work on alot of other low-end machines that customers can bring into shop as i don't carry many parts for other machines and i'm a 1-man service dept. good luck to you kj and have a safe new year.
cool!! but i have to ask, are you a packers or lions fan? i know you "upers" areotorious for being packer fans. please tell me you're not one. lol!
