Canon ir c5185 losing laser settings

[pontiac]

We have 5185 that loses it's laser settings about every three days. The copier is left on 24/7, options include fax, print and scan. I re-enter the laser settings , perform gradation and copy quality is restored. Any thoughts on what keeps causing this?. Thanks

give us an example of the random laser settings.

Are they much higher or lower than they should be?

pve-ofst setting may start off -12 but changes it's setting to 0 all laser settings change to 0 and i have to re-enter all of them.

only thing i can think of is a dead or dying backup battery, possibly on main controller or laser driver

change your service mode to *49* to eliminate someone messing with it.

PVE-OFST/ this number should be entered from your original service print/

did u run FULL AUTO-GRADATION -after entering laser label numbers-
Did u check the ITB Reference Patches/& Correction Patterns- on power up ???


what did your images/issue look like before settings change (CQ,PRINTER ERRORS ??)
