Re: Canon IR5180 registration issues

this is a normal PG10 /BELOW- your's is off /black bar should be on both ends
five black/four yellow/four magenta/four cyan -bars

pg10.JPG

u have an extra magenta bar on top of black/see below
++ bottom black bar too narrow/
now it's a off-set main scan issue on Black/front to back

Go back in to the Laser units/
u don't have to remove them
Use the appropriate service mode (with the corresponding color) to enter the values shown on the label affixed on the top of the laser unit.
Laser Manufacturer ID:
[1]COPIER > ADJUST > LASER > LA-MK-Y/M/C/K
Laser Magnification:
[2]COPIER > ADJUST > LASER > LDADJ1-Y/M/C/K
[3]COPIER > ADJUST > LASER > LDADJ2-Y/M/C/K

Re: Canon IR5180 registration issues

good observation Techat, I did check the labels on the lasers , but I only payed attention to the green and maroon areas they were pretty constant between all lasers. almost all were something like 0 -0 -0 428 256 652 each one was off a digit. I think the areas in blue were the first 4 entries which were all 1. all were in level 1 service mode. So there is a door spec sheet somewhere on the machine, It's behind the reader unit in the front? I did not do a rcon clear I just did a dccon clear.

Re: Canon IR5180 registration issues

Tecket, did you see the last pdf that is labeled after door specs entered? notice the black bar extends higher than the y,m,c the bottom is cut off but it is shorter than the others.

Re: Canon IR5180 registration issues

i am still trying to figure out that extra magenta bar.
I see the black issue/ u see the black edge bar shift from main scan toward the rear/
is the black bar on you PG10 shifted from the front also ?

if so , this is caused by the corrective lens /correction motor-operation
Laser_main scan.JPG

put in your exact Laser Label numbers/power off-on printer / run a full auto gradation
if u receive a message calibration page not recognized ,
it's because of the image block shift of colors on page
-
print out a PG10/ to inspect>if still off line/ Swap Black Laser with another Color, don't worry about the label numbers/ POWER OFF-ON- print out a PG10 see if black issue shifts to other color ----- report back

Re: Canon IR5180 registration issues

I had cleared dccon and the image looked better but when I re- entered the door specs thats when the black shifted. Yes, the black bar shifted in on pg. 10 on the front side. It looks like the laser assy had shifted!! yesterday, I swapped lasers ( black and magenta) and re-entered the door specs. with no change at all, I did not receive any message after doing a full gradation!

Re: Canon IR5180 registration issues

u swapped Lasers and the Black shift issue stayed on black ?

i hope u did not unscrew the screws marked with red glue on each laser/ one each on each laser unit- once these are moved u loose the locked in position from manufacture product specs .

u will then need to play with the angle set position of each

post a PG6 GRID PATTERN

Re: Canon IR5180 registration issues

correct!!!

Re: Canon IR5180 registration issues

Did u touch those red glue screws ??

try to reload your firmware / overwrite all if prompted

[acsolutions]

Re: Canon IR5180 registration issues

yes, I did accidentally loosen the screw on the black unit only when I was pulling the units out to align the cams, black unit only! but this would not cause the black to shift and add an extra magenta bar! when I re-aligned the laser I used pg.10 as a guide to compensate for the skew, I did not submit the that page when that adjustment it adjusts for skew.

Re: Canon IR5180 registration issues

i faced similar issue. have you swapped the ITB assly to another machine and checked ??
my problem solved after complete cleaning of ITB assembly rubber rollers and also primary transfer rollers. I used WD40 to clean the rubber rollers with clean cotton swiping in one direction only. a lot of dirt/toner gets into this and cause slipping of the belt and gives registratiion issues . this is for sub scanning problem only.

Re: Canon IR5180 registration issues

i know the screw fix is for slant recovery/ many techs have moved that screw,
& called me out to the customer not realizing what they have done/

post a PG 6 GRID PRINT OUT/ Did u check those RCON settings behind reader panel ??

Re: Canon IR5180 registration issues

Laser Main Scanning Write Start Position Adjustment
COPIER > ADJUST > LASER > PVE-OFST

what is your #

Correcting the Angle in Main Scanning Direction
The Bk pattern is used as the reference.
The machine identifies the angle in main scanning direction with reference to front/rear discrepancies of individual colors.

The machine compares the length of the center line of the Bk image position correction pattern (front) and the length of the center line of the image position correction pattern (front) of individual colors, and identifies the difference between the two as the degree of color displacement in main scanning direction

have u tried a new black drum ???
DC controller ?? Main Scan Video signals transfer to Laser unit

Re: Canon IR5180 registration issues

I did not check the settings behind the reader panel as of yet, the only info I had on the machine was a 4 year old pprint in the front cover. I did not realize there was a spec sheet behind the reader cover until yesterday, after I left the account! that I will have to check next week. The only thing that I have replaced so far is a used ITB assembly which made no difference.
