Question about Ricoh Aficio 250 Copier

1 Answer

Hello everyone. I just replaced the polygon mirror on my Savin 2515 and the copier is again operational, however I noticed that the output is not as sharp and crisp as it was before the failure. I did not touch any of the mirror's surfaces during replacement (although I do not remember if I left any fingerprints on any other reflective surfaces.) Could it be that the new unit requires some kind of alignment? (I noticed that there were tamper detection marks on the screws when I removed the old unit; a sign that replacement requires something more that only a technician would know?) Any feedback would be much appreciated.

Hi chro,
Send me an e-mail and I will send you the whole manual. I will give you my email address now,but it will look funny because "fixya" has an email filter to make sure we can't do what we are gonna do. jdh6211#####comcast#####net. If you can figure it out you win. I'll be watching. But you DO indeed have some fine tuning to do. Service mode and all that.

Funtion problem

Sc 322 means there is a problem with the laser unit,and 99% of the time it is the polygon mirror motor within the laser unit. You have 2 options.Replace the entire laser unit which is in a neat little black box and is relatively easy to replace. Better yet,merely replace the mirror motor which is enclosed within the laser unit. But one or the other must be replaced as there is no adjust/oil/clean/tinker/fudge to be done. I wish I had better news but really the news aint bad and the advice is free so if you have to get "copier dude" to come out he/she wont try to hose you !!! Well they might try,but YOU know better. :-) hope this helps,take care. .......spinal.......
