Hi how you doing the main problem with changing the dev bias is that the gap between the drum charge and dev bias has been brought closer and so more toner is being put onto the drum for image density.. I take it you have cleaned the optics on the scanner mirrrors and that the laser **** glass has been cleaned as these effect the copy quality too.. if the dev hasnt been changed at the pm intervals it slowly looses its charge holding capabilities.. you should change at least at the 160k marks to keep quality good.. you could also adjust the laser power up so you have a stronger image formation..hope this helps..if you know the machine I would take the laser unit out too and take the cover off to see if there a dust coating in the image mirrors as this can cause faint copies over a long period.. Good Luck A
Hello sir; Just follow the steps;
1, dump entire dv use vaccunm cleaner to cleanup don't leave any dv inside.
2, thorughly clean out magnet roller by rubbing alcohal.
3, pour in new dv evenly.
4.Do simulation 2801 & 2805, the procedure as follow;
press"clear mode", "107", press and hold "clear/stop" key for 3 seconds, then press 1 for copier sp then enter2801 press start, after that go to 2805. same procedure. Let me know the resolve.
Enter SP mode - Clear button (yellow key), 1 0 7 and hold and press stop button (orange key).
Enter SP5-810 (SC code reset) and select “1”.
Then hold down the “Photo mode” key and the enter key(hash) at the same time for at least 3 seconds (it is not necessary to turn the main switch off andon). If the machine beeps 5 times, the reset was successful. If it only beeps twice, the reset failed, and you need to repair the machine.
Possible causes are the fusing thermistor in the fuser unit, or the power supply unit defective.
Good luck and please rate me, thanks.
You have a problem in the heater, sensors detected temps over 220c for more than 6 seconds. It will be an expensive repair. Most likely around $400 parts plus labor. Not something for the average Joe to troubleshoot.
