View Full Version : mita 1470
I have a machine that seems to be warming up & then the heat lamp cycles on & off like it should but it won't come to ready. Seems like I've seen this a long time ago but don't remember what it was. Any ideas? tia.
tom, is it continuosly rotating? have you seen it flashing "AP" on display? if so, its trying to add toner to get back up to the correct density. this happens if customer runs a few copies with "add toner" light on or developer/processing unit is getting very close to 30k or its running quite dark. if this isn't what it is, write back with as many symptoms as you can and i'll see if i can help.
good luck,

No AP message or code of any kind. Machine warms up, cycles for a while then stops like it has come to ready, but it never lets you print. I know its not the print button because it wont take on manual byp*ss either.
while pressing the print key and stop/clear key at the same time, turn on main power switch, then within 2 secs, let up on stop/clear key and then press stop/clear again. you should be in simulation mode. enter "02" for copying with no paper, put 11 by 17 white original on gl*ss, open paper c*ssette, select copy mode and press print. while its running, check to see if CN7-6 on main board and CN7-7 go low. if they don't, you're looking at a main bd. problem. CN7-6 checks the paper feed clutch signal and CN7-7 checks the registration clutch. thats the next thing i would check anyways.
good luck and let me know,

Try removing the main charge corona *ssembly, then press print. The corona's are known for arcing and causing weird problems. You may have to do U70 to clear machine. Then redoing U60 with the toner cartridge removed. You may have to adjust other things as well.

Figured it out. There was a small piece of paper wadded up over the sensor in the Doc. feeder. Strange in that it didn't give a jam signal or anything, just wouldn't come to ready. Removed it & it worked fine. Copiers, don't you just love 'em.
