Excess Black Toner IR C5185

[Guest]

Hello,

First time posting here. We have replaced several parts on this printer before. Most recently a new transfer belt, fixing assembly, black drum, black toner. Here is my problem. When printing out a job, I have noticed that there is just one side of the card where an excess of black toner is left on the paper. This only occurs when we are printing on heavy card stock paper (80 lb. cover). When plain paper is selected.. there is no excess toner. We have cleaned the transfer belt, as well as everywhere in the machine that we can reach. Any ideas? Any help is appreciated. Feel free to let me know if any additional information is needed. Thanks! Attached is an example of what we are getting. - Also, we have noticed it helps if we select the "Clean inside main unit" in between a job. This starts the job with minimal excess toner, and increases as the job continues.

Ok. Tried cleaning the transfer cleaning blade.. put the transfer belt back into the machine, but now the belt will not spin. The gears that turn the belt spin, but the belt itself does not spin.. any ideas?

Re: Excess Black Toner IR C5185

Totally cleaning that blade is not a good idea.
It comes heavily pre-lubed, so you have to lube it again preferably with TOPPEARL.
Your best bet is to change it.
THey eventually get to a point where they cannot be salvaged.

Hopefully you cleaned the drive roller and internal secondary transfer roller when you replaced the belt.

PAPER FEED.JPG
paper types that can be used with this machine are shown below

Stack Bypass
(17 lb bond to 140 lb index (64 to 253 g/m2)
Heavy 1 paper =28 lb bond to 110 lb index (106 to 209 g/m2).
Heavy 2 paper=110 to 140 lb index (210 to 253 g/m2).

Paper Drawer
(17 lb bond to 110 lb index (64 to 209 g/m2)
Heavy 1 paper from 28 lb bond to 110 lb index (106 to 209 g/m2).
u can not use Paper Drawer for>
Heavy 2 paper =110 to 140 lb index (210 to 253 g/m2).

Paper Deck
(17 lb bond to 110 lb index (64 to 209 g/m2)
Heavy 1 paper from 28 lb bond to 110 lb index (106 to 209 g/m2).
u can not use Paper Deck for
Heavy 2 paper=110 to 140 lb index (210 to 253 g/m2).




when u select "HEAVY" 1 or 2 /are u running paper from Manual Feed Tray ? or Deck ?
80lb Cover 218g/m2
When 79.01 system software for the C5185 Series was released mid 2008 on technical publication TP08 094d.pdf, there were additional service mode settings added. They are as follows:

Level 2 > COPIER > OPTION > BODY > REG-SPD (Plain Paper)
Level 2 > COPIER > OPTION > BODY > REG-SPD2 (Heavy Paper)
Level 2 > COPIER > OPTION > BODY > REG-SPD3 (Transparency / Glossy Paper)

These service mode settings are responsible for the registration roller speed adjustment.

1-The paper arch created between the 2nd Transfer Roller and the Fixing Assembly may be too great.
Increase the fixing speed for heavy media with >
Service Mode LEVEL 2/ COPIER>OPTION>BODY>FX-SPEED2 (the larger the value the faster the fixing speed).
The setting range is from -5 to +5 (the more positive the faster the registration speed).
If your issue is on trail edge try a decrease to -4

SERVICE MODE LEVEL 1
press Additional Functions Key (once)
press #2 & 8 key at the same time (release both)
then press Additional Functions Key again (release it)
for Service Mode LEVEL 2
press Additional Functions Key again/then press #2 Key


if results for FX-SPEED are poor>
I would swap the BLACK LASER with another Color to Start-

next I would check out that back link that was posted by/vigour

Bingo.. That was my problem. I lubed it up with excess toner and the belt is back to normal. Ordering a new cleaning blade..

Teckat, I believe it's the trail edge that's getting the extra toner dumped onto it. It's the edge that prints facing the back of the machine.. I always feed it through the paper drawer. 80 lb cover.

I also cleaned many of the other rollers very well. This cleared the problem for about 200 pages or so.. but the problem came right back. My last guess is a possible bad drum? However, the drum was just replaced 3 - 4 days ago.

Are u using OEM Canon toner & OEM Drum ??
to me Back of printer is not Trail Edge/ that is REAR as shown in pic above---
if your issue is on BLACK ONLY I would look past the cleaning blade-
when u see the issue appear > pull out the BLACK DRUM to inspect surface

Canon explains paper direction different in manual when it shows the BLANK EDGE Adjustments/as (RIGHT-LEFT-TOP-BOTTOM

my description is basic on posted pic above---
when paper exits face up into the delivery tray on a 5185 /
side facing control panel is FRONT>
side facing back of printer is REAR>
direction paper exits fuser is Paper Feed> opposite that is Trail Edge

Re: Excess Black Toner IR C5185

Yes OEM toner/drums always. The drum does look a bit worn, however it only has 27% Life used on it.. We have received bad drums in the past, but is this pretty common..? Please note our machine has over 2 million prints on it now (after replacing several parts of course). If having drums go bad within a day or two is uncommon, would the age/ work the machine has done be some sort of reason for drums to go bad so quickly? Thank you all for your help so far.

Point to note:

these Drums are tested for a 5/6% coverage of text / see attach example--


Drum Life all depends on % of toner coverage on paper=heavy color usage beats the hell out of drum surface/ first sign is usually background>then a wash of toner dropping on ITB & Interior--

You should be sending that 80lb Cover through the bypass .
You are curling up the trail edge when feeding from the cassette

Re: Excess Black Toner IR C5185

the edge that faces the Back of Printer is not the Trail Edge

Re: Excess Black Toner IR C5185

Thank you all for the help. Just an F.Y.I. for anyone experiencing the same issue..

-The excess toner was caused by a bad drum i guess.. only had about 60% life used, but swapped it out with a new one and all was fixed.

-As for the belt stopping after i cleaned some parts/ transfer belt, cleaning blade.. etc.. What i did wrong was completely wipe the blade clean with alcohol.. which is a big no no. Lubricated it with a bit of toner and it was back to normal.

thing to remember about drum life use % shown on control panel>>>
this does not reflect the amount of toner coverage/used on each page printed --

Canon still has a hard time explaining this % use, they even had firmware updates that were useless/


To disable the Remaining Drum Life Screen, perform the following. COPIER > OPTION > BODY > DLIFE-SW > 0

I have had a black laser unit lay down to much toner on the page on this model. It kicked me in the *** until i replaced it. You can swap laser units with another one to test. If you do you might want to put the values on the sticker on the laser in the service mode.
