Canon IR5180 registration issues

Re: Canon IR5180 registration issues

Reader label is for RCON settings/ a four year old P Print-that is amazing,just imagine all the changes made in service mode in four years after that, and not recorded-

I tell all my techs to keep the original spec settings sheet under that cover & never move it/
have them print out P Print settings after any new install after changes made.

good luck next week

Thanks again for your assistance.

Re: Canon IR5180 registration issues

question, when I did a dccon clear would this adjust the adj-xy and ccd settings. the printout I had in the machine had these settings blank. Before I did a dccon clear I did not make a pprint. would dccon clear effect these settings and if they did how would get them back? Also, which board are the door specs. stored on?

[teckat]

Re: Canon IR5180 registration issues

Dcon specs are stored on P Print or in original papers from printer
RCON specs are inside reader cover

ADJ should not be blank/ u need a MANUAL

Re: Canon IR5180 registration issues

hey Teckat, I found the specs behind the reader cover and the adj-xy and ccd settings were on the label. All the specs. were correct, the laser specs and the PVE-OFST setting you asked for was -23. No I did not replace the black drum unit, DC controller or video signals transfer to laser unit. but after doing a dccon clear and adjusting the laser PVE-OFST and using the #6 print to adjust for the black laser skew the prints look great!! Now, the original setting for PVE-OFST was -23 and I set it to +2 which brought it into spec. what would cause this? what would wear to cause me to compensate for this? another question is in MISC/for drum unit life y=496 m=499 c=509 k=516 what does this mean? I told the customer what I did to fix the problem and that I was going in investigate why this setting was so far off. customer says this is the best the print has looked in years. Thanks for hanging in there with me Teckat

Re: Canon IR5180 registration issues

the drum life counters you have posted here are all very high. I would suspect that the drums will need replacement very soon.

Re: Canon IR5180 registration issues

Thanks,
Replace all those Drums Now,
Don't know why PVE-OFST was out of wack !!

Have u been the only person servicing this printer ????

Print out two copies of P-PRINTS and User Data sheets/ keep one set of both under cover- give other set to customer

Re: Canon IR5180 registration issues

having same problem have done all suggested items here also swapped uot or replaced dcon 1 dcon2 on order replaced main controller, salt sensor, itb asmbly, wiper, will let u know if masiy pcb takes care of it will also order itb drive copier has about 2m on it.

Re: Canon IR5180 registration issues

you have a slant issue ??

post some PG 10's & PG 6's
your taking a shotgun approach / that is replacing/swapping too many things at once

approach is to isolate the issue first-

Re: Canon IR5180 registration issues

Hey Teckat, Yes this is my first service call at this machine. Its a gov. account and there only allowing me out until this service call is complete. I'm not sure if I'll be visiting their again! The customer wants this machine to last another year. They have 375,000 copies and all there drum units are bad. Do you have any suggestions on what parts I should pm the machine with to get them by for a year? Thanks again

Re: Canon IR5180 registration issues

replace all drums
replace ITB cleaning blade unit
replace Sec.trans.roller
check all paper feed rollers
how old is the fix unit ?? refurb ones cost $800.00
how old is ITB SHEET ??

SKMBT_C25211071516240.pdf Hey back again! got a callback on this image the yellow is slanted, not sure if I should check the laser cam or adjust the laser slant? you really cant tell by looking at the grid with a naked eye but I found a glass and can see how it starts at the top and gradually blends in with all the othe colors. I did not touch the adjustment screw for that laser, just the black and it was tough to center.

Re: Canon IR5180 registration issues

First replace all drums

The following factors can displace images of individual colors:
- displacement of the photosensitive drum caused by replacement of the drum unit/toner container
->displacement in sub scanning direction
- displacement of laser path caused by replacement of laser unit
->displacement/angle in main scanning direction
- displacement in laser path length caused by changes in temperature inside machine
->variation in magnification
To correct the discrepancies in images, the machine executes corrective control for image position; it detects displacement in color by forming a pattern of a specific
color on the transfer belt and reading it against the correct position.

Detecting/Correcting Color Displacement in Sub Scanning Direction
The YELLOW pattern is used as the reference. The machine identifies the degree of color displacement in sub scanning direction with reference to the timing at which other color patterns are checked after a check on the Y pattern.
If the timing is not correct, the machine corrects the laser write start timing in sub scanning direction.



I think it's time to place a Call for a Canon Authorized iR5180 trained tech.

Re: Canon IR5180 registration issues

these factors will cause a skew? I thought black was used as the reference? I guess I will start with the drums!

The YELLOW pattern is used as the reference. The machine identifies the degree of color displacement in sub scanning direction with reference to the timing at which other color patterns are checked after a check on the Y pattern.
If the timing is not correct, the machine corrects the laser write start timing in sub scanning direction.This would not cause the laser to write skewed, correct?I think it's time to place a Call for a Canon Authorized iR5180 trained tech. NOT AN OPTION!

Main Scanning Direction
The BLACK patternis used as the reference.

Sub-Scanning Direction
The YELLOW pattern is used as the reference.

Just replace all the Drums-
u will never accomplish anything with old drums/
u need to establish a starting point maintenance procedure

LD-ADJ-Y/M/C Making the tilt correction motor return to the initial position automatically.
Operating Instructions=
1) Select this mode.
2) Press the OK key.
- The operation starts. It automatically stops when it is completed.
Reference:
The tilt correction motor may get locked when the tilt amount in the horizontal scanning direction exceeds the expected range, and consequently color displacement cannot be corrected even though automatic registration is conducted.
When this symptom occurs, use this mode to make the tilt correction motor return to the center position automatically.
(If you try to do this operation manually by opening the scanner unit, you may touch the lens. For this reason, be sure to do it by the automatic operation.)
This Service Mode is used to correct the tilt of Y, M, and C against BK, which is used as a reference, when the tilt is
large (when the horizontal lines are higher at the right).
