An ipf8300 is creating smears on the right edge of the paper when scanning the paper. It looks like ink drops and not like head streaks. How can this be resolved?

Re: Ipf8300 smear/ink drops on edge of paper
small picture try uploading in PDF
what are the page counts on the PH's?
page counts on service station?
have you cleaned the machine?
original OEM inks?
have you done ANYTHING to the machine?
you give little info for us to help you.
are you an end user?

Re: Ipf8300 smear/ink drops on edge of paper
I think that I would make an attempt to clean the bottom of the carriage, which often builds up with overspray of ink. You may be able to do enough cleaning without completely removing the carriage from the rail. Cotton swabs and alcohol.
It's a relatively major task to remove the carriage to turn it upside-down for cleaning. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: Ipf8300 smear/ink drops on edge of paper
* take the head out w/ power off.. gently clean w/ soft lint free cloth
* clean the service station with QTips pay attention to the drop sensor if clouded over it could push more ink thru the head during drop test.
since local tech refuses to service you (did you contact his boss) I would post in the the Service Manual Request forum to see if someone will share their manuals with you.
once you have manuals and have cleaned the printer perform: all calibration and head gap tests...
it is a concern that the head/carriage is banging into somethingComment

Re: Ipf8300 smear/ink drops on edge of paper
Thanks for your response
).
I have seen that cleaning under the carriage requires a lot of disassembling...
I will try to clean the carriage unit with a cotton swab.
I have uploaded a video where you can see the carriage unit hitting the platen. This happens at the beginning (where the ink lines occur) and in the middle of the platen. At the middle part it can be seen that the right part of the platen is raised a little bit, which should be responsible for the strange sound that you can hear in the video. Is it normal for the carriage unit to drive so low at startup?

Thanks for your response ).
I will try to follow the steps of cleaning, when I get my hands on the service manual for the machine.
Here is a video of the carriage unit hitting the platen on startup. Is it normal for the carriage unit to drive so low? Maybe gap calibration will help (As also mentioned by you)?

Re: Ipf8300 smear/ink drops on edge of paper
Is the load paper handle in the down position? I don't think it's the platen, possibly the white idlers that hold the paper. If the handle is raised, so are the white idlers. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.

Re: Ipf8300 smear/ink drops on edge of paper
Also as Blackcat said wipe the underside of carriage assm.
Head gap can get off if settings were set back to factory. ( esp if used enough)
So the machine determined via setting stored. (head gap... quality settings etc)
Just wondering, are most of your prints (even proofs) done in HIGH QUALITY mode that lays down more in which could also be issue related.
As far as media.. are yours in the "APPROVED" list?

Re: Ipf8300 smear/ink drops on edge of paper
Hello Phil,
I think I have narrowed down the issue. I did the gap calibration, which had no influence, the carriage unit still strikes the paper in the middle and at the beginning. I then changed the head height to every position and inserted my sheet. The head position stood the same!!! The head did not raise a bit (at max it should be at 3mm)! I could see that very clearly when I did the nozzle check pos. The head went to max position, I guess (gap was relatively large). So it seems that the head height doesn't change when I adjust the media in the settings of the printer. Did you ever come across this issue? EDIT: I also noticed, that the head height only changes when printing (tested with test prints) and not when inserting media (which then, on head height: low, ruins the paper with ink). Shouldn't the head height also change when inserting the media, so the print head doesn't jam (on canvas for example)? Is this intentional by canon or a machine error?
My media is on the approved list and I have seen other people use that media on that machine.

The handle is down. No worries.

Re: Ipf8300 smear/ink drops on edge of paper
Hello guys!
I did some more testing today and found a weird behaviour, which explains the streaks on the paper.
I inserted the cut sheet as "roll paper" by accident and saw, that the head height at measurement (paper loading) was high above the paper (setting set to max for testing purpose).
When I inserted the cut sheet as "cut sheet" the head was very low and scratched the paper.
The settings for the paper were the exactly the same. So there might be a setting missing, which adjusts the height of the head when a cut sheet is inserted. Do you guys have seen something like this?
Furthermore, I noticed, that the head scratches the platen on both settings "cut sheet" & "roll" (when no paper is inserted into the printer and the printer is in startup mode!).
Sincerely Marcel)
