Hi Dag,

The users tried new paper yesterday, the paper is what we have been using since we have been using it.

Thanks dag.

Latest Update

After trying what TekCat suggested:

With a Plain blank I made 5 copies fine, then reset counter 10 to and the first page was wrinkled, no others in that lot.

then I tried enlarging made 3 copies going from 8.5 * 11 to 11 * 17 no wrinkling. (enlargement was @ 115%
switched back to 8.5 * 11 for paper and first page was wrinkled.

So what else need I check, (should I just get a piece of C-4 and take care of it LOL)

I also took the ITB out and checked to make sure it was not skewed or pulling to 1 side or the other, as far as I could tell it was normal and running true to tracking.
------------------------------------------------------------

Thanks again for all the assistance and help.

new ream of LETTER sounds like a solution test--

is this what u did ____
when u place 11x17 on glass and run a Reduction to Letter paper do u get wrinkles ??

when u place a business card on glass and run Enlargement to Letter paper do u get wrinkles ??

this is testing correct speed path to fixing

Re: Canon IR C5051 Copies comingout Wrinkled

Actually Tek,

I took an 8.5 * 11 and enlarged it to 115% onto 11 * 17 paper & 8.5 * 11 paper.

Didn't get wrinkles on 11 * 17 but did on 8.5 * 11.

Never did reduction test, since it was wrinkling on the enlargement test. figured it would do it that way also.

Last Update until MOnday.

Went into Service mode and ran NIP-CHK, gave NG! message on screen.

Have already ordered Pressure Roller, and Fixing Inlet Guide.

Anything Else I might need to try?

Thanks again, your assistance is truly appreciated.

=======================================

No---u probably have done this below-

Check the fixing entry guide for toner build up and check the fixing NIP for even pressure.

If these are normal, check the guide plate in the Shutter Assembly for toner build up. If present, remove the toner or replace the shutter assembly: FM3-5952-000.

Re: Canon IR C5051 Copies comingout Wrinkled

How do I check the fixing NIP for even pressure.

I went into service mode>> function>>> Fixing>>> NIP CHK,
When I pressed OK it came up with NG! on the screen.

Is there any other way to check the NIP Pressure??

thanks again.

========================

NG Means u have an ISSUE to inspect


Film unit, pressure roller
Check that the fixing nip width is within the specified range.
Paper to be used: A4 / LTR size (plain paper, 80 to 105 g/m2)
1) Set paper on the manual feed pickup tray.
2) Execute output of fixing nip paper in Service Mode:COPIER > FUNCTION > FIXING > NIP-CHK
Paper is picked up to make 2-sided print.
1st side: solid image in Magenta, 2nd side: no image (blank)
The paper is stopped at the nip area when fixing is performed on the 2nd side, and then delivered outside the machine approx. 15 sec later.
3) Measure the nip width and check that the measured value is within the specified range.
NIP.JPG
Specified value (range):
Center: 9.0 -/+ 1.0mm
Edge (145mm from the center of feeding paper): 9.0 -/+ 1.0mm
If measured value is out of the specified range, reinstall the replaced parts (film unit or
pressure roller) and then measure the nip width again.
MEMO:
Fixing nip width cannot be adjusted in the field

Re: Canon IR C5051 Copies comingout Wrinkled

Ok. Lets get some info straight here. Do you mean wrinkling like a crease in paper feed direction or ripples/waves in the paper from front to rear of the copier? Also..you say only on letter....ltr from all cassettes and bypass? Just a specific tray? Gotta find out your definition of wrinkle..might be a paper feed issue. Is image skewed at all on creased sheets(lead edge and trail edge)? If it is a wrinkle(feed direction) is image transfered over crease or tucked inside crease

Hi Canuck,

Ok It is a crease that starts at the leading edge (approximately in middle of page) and travels about 2 -3 Inches diagonally from left to right.

As far as I can tell it is with all cassettes that use letter (1 & 4) have not tried the bypass tray.

No Skewing of image on the page, it is true as far as I can tell.

I have printed 11 * 17 pages and do not get any creasing.

===============================


did u test LETTER PAPER in LTR-R feed direction from cassette ??

bypass test>
fixing speed does not match the paper size in travel speed

Print speed (ppm)
Paper length in width direction
---------------------------------------
Temperature at the edge of the film is increased when continuously making prints. Excessive
temperature rise can deteriorate the film. When small size paper (A4R or shorter size in width
direction) is printed, the mode changes to the down sequence.

When making prints with paper that is A4R or longer and A3 or shorter in width direction while
the film temperature exceeds the specified temperature (sub thermistor 1,2), the fan attached
near the fixing assembly sends air and cools the film to control temperature rise. Unlike down
sequence, this control will not reduce the through-put because this control is executed while
printing is continued.

There is a shutter at the air vent, which moves (opens) in 7 levels according to the size of
feeding paper. This feature enables to send air to optimal area on the film.



• Down sequence when switching paper size
Purpose:
This down sequence prevents temperature rise of non-feeding area: there can be possible fixing offset or wrinkle of the succeeding paper due to increased temperature of non-feeding area of the preceding paper when continuously making prints or feeding wider length of paper than the preceding paper.

PW.JPGStarting conditions:
If the detected temperature of sub thermistor 1 or 2 exceeds the specified temperature
(250~260 deg C) when switching to the paper which has longer width than the preceding paper.
Operation:
Pickup of the succeeding paper and power distribution to the heater are stopped as well.

Completion conditions:
This down sequence is completed if any of the following conditions is satisfied:
• When the detected temperature of sub thermistor 1 or 2 reaches the specified temperature or less.
• When the specified period of time*1 has passed since the preceding paper went
through the fixing nip.
*1: Specified period of time differs whether the fan has cooled the preceding paper or not.
• If the preceding paper is A4R or larger and A3 or smaller (the fan has cooled the paper)
→ 15 seconds
• If the preceding paper is smaller than A4R (the fan has not cooled the paper)
→ 30 seconds

• Setting for down sequence start temperature when feeding small size paper
COPIER > OPTION > IMG-SPD > FX-D-TMP
<Setting value>
-3: -15 deg C
-2: -10 deg C
-1: -5 deg C
0: 0 deg C [Default]

Re: Canon IR C5051 Copies comingout Wrinkled

Hi Tek Cat:

"Film unit, pressure roller
Check that the fixing nip width is within the specified range."

I tried to run the Fixing Nip check,

When I run it, it jams and causes a crease when in the process of doing the second side of the copy.

Also the toner is not on the page correctly (based on what I understand from the explanation).

There is about a 1 -2 inch area on the leading edge where there is no toner then it goes all the way to the trailing edge.

Not 100% sure if this is what it is supposed to look like because I can't view the pic you included in the comment above, (it shows up with an X on it and won't show when U rt. click and click show picture.).

I have already got the pressure roller and fixing inlet guide on order (should be in today or tomorrow.).


Will replace them and then see if we still have the same issue.

Thanks for all the comments and suggestions to try.
