7105 Fuser Web not Turning

[shazza]

Hi All,

Any ideas for following problem?

Web not turning on a ir7105. Previous Engineer has replaced Fixing assy Complete and replaced Dc Controller. No error codes just eat up UFR after about 40K


Thanks,

Shazza

Have you checked if the web solenoid drive signal is being generated by the DC controller PCB? If you verify that signal----does the solenoid SL12 operate? Actuate the solenoid by hand to see if the gears that drive the web advance.

To add to Blaze's advice, go into Service Mode, Parts Check and pick that solenoid and have the DC Controller doing the picking, which tests out the entire scheme. If the solenoid is not being activated, then you can start with the physical investigation...

fixing web solenoid is FL2-3531-000

Hi,

The web solenoid actuates and winds the web if done by hand. The complete fixing assy has been replaced and it works for a while then stops winding on.

The solenoid is part of the assy so thats new, I will let the Engineer know to check signal again but he says its ok!?

Cheers.

Doesn't the web unit have to Cam away from UFR while Printing ?? if it does not and always sits on UFR the web take up supply will not function /

FIXING WEB DRIVE ASSEMBLY = FM2-6128-000 > has that Cam

The web is in constant contact with the upper fuser roller,,, I
can't think of any model that does not operate in this manner...

The cam you have highlighted is the one that moves the thermistor back and forth on the upper fuser roller to prevent putting a wear band on the UFR.

sorry, but u are wrong = Example- the CLC's series web units Cam up while printing

Does anything other than the CLC 5000 series do that? I was only trained on 1100 series. The 7105 does not lift the web away from the UFR...

[teckat]

CLC 5000 SERIES had two webs/ for UFR the Web Cams Away/ for Lower FR- Web is fixed against roller at all times

The highlighted area does not state what is happening when SL4 is turned on. Could be anything.....like initial rotation, perhaps.

sorry the picture above is for a CLC/ it was in response to posters previous question about the big Color CLC's web advance.

SL4 releases Upper Web unit away from UFR before paper enters Fuser Rollers / it is a continuous action while printing. u can view operation, by removing front fuser cover-open door -& key up machine , to watch

[MichaelConway]

As you know the question was based upon a Canon iR7105, a B&W copier. Thanks for the followup!

[teckat]

sorry for mix up/ do u know what that Cam/Gear on 7105 fix clean unit does/ or is for ??

Allow me to quote from my distinguished colleague from the great state of Iowa, "The cam you have highlighted is the one that moves the thermistor back and forth on the upper fuser roller to prevent putting a wear band on the UFR."
