I'm needing instructions on how to assemble/disassemble the fuser unit on a C3170. Does anyone know where I can purchase a downloadable manual, I don't see Canon on manuals4you.com
Thanks.
Thanks.

If you compare what those 2 fuser rollers will cost you to the price of a new fuser I think you will find its easier and won't cost that much more to replace the fuser assembly. And - don't forget to go to service mode level 2 and turn on DWNSQ to keep rollers from going flat.
Level 2
COPIER > OPTION > BODY > DWNSQ-SW
1: down sequence enabled.
0: down sequence disabled (default)
c. Prevention of Partial Deformation of the Roller (otherwise caused by no use over time)
The fixing roller can start to suffer deformation if left alone for a long time under
temperature control (because of its nip). To prevent deformation, the machine rotates the
fixing roller at 68.5 mm/sec (half speed) for a period of 0.5 sec every 30 min

just buy a new one. The fuser on this machine is a pain to rebuild no matter how many times you attempt it and since it mostly plastic something will break during the process making it irrepairable and needing replacement anyway.
Save yourself the time and headache!!!Accidents don't just happen. They must be carelessly planned.Comment

DWNSQ-SW /Level2=is not available on 3100 series
unless it was added in a firmware update**Knowledge is time consuming, exhausting and costly for a trained Tech.**

The method I posted for DWNSQ was copied and pasted from the IR C3100 Canon service manual revision 0 , January 2004. Page 9-11. I can't imagine that the 3170 doesn't have the same adjustment as the machine is newer than the 3100 and I think I did this adjustment to a 3170 a couple of weeks ago if memory serves me right. Your european service bulletin is from 2006 which is newer than my manual and should be the current info-----all in all -----curious indeed.
The C3100 intro date was April 2004 so as to it being in a firmware update.....no way. The origional firmware / intro date of the machine and date of my manual (Jan 2004) coincide and would make it a feature available from the beginning.Last edited by blazebusiness; 05-10-2011, 11:45 PM.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

under COPIER > OPTION > BODY>DWNSQ-SW , it states "not used" in 2005 manual
don't work on this model anymore, but after reading below , recall that setting was for Curling issue ???
but then it is available -in chapter 9/ 9-8
COPIER > OPTION > BODY > DWNSQ-SW (Level 2)
1: down sequence enabled
0: down sequence disabled (default)
Speed Control for Printing Volume (down sequence)
To prevent the symptom, the machine permits a change to the service mode settings so that the following takes place: after the 100th sheet in large size mode or after the 200th sheet in small size mode, the machine increases the distance between sheets and reduces the printing speed by half to decrease curling and ensuring good stacking. The machine refers to the counter reading for the sequence, not to the roller temperature reading.
c. Prevention of Partial Deformation of the Roller (otherwise caused by no use over time)
The fixing roller can start to suffer deformation if left alone for a long time under temperature control (because of its nip). To prevent deformation, the machine rotates the fixing roller at 68.5 mm/sec (half speed) for a period of 0.5 sec every 30 min (during standby).
When the machine starts sleep mode, the machine turns off the power to the fixing motor (M11) to prevent the fixing motor from rotating; however, since the machine does not perform temperature control for fixing in sleep mode, the roller will not suffer deformation even when it remains stationary.
The machine performs temperature control for fixing while it is in power save mode (-50%) or in low-power mode, and turns off the power to the fixing motor (M11), thus preventing the fixing roller from rotating. If such a condition lasts for 4 hr or more, the roller can start to suffer deformation; the machine, however, is designed to shift to sleep mode before the passage of 4 hr so that the roller cannot start to suffer deformation.**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

this series has been having issues with flat spots for the past six years, a fact of life
when I worked on this model>
I used to check the nip width on all new units , some were way off**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment
