helo very body please l have a broblem in canon ir c 2880 when make copy line apear in apaper but when l print from computer it's a clean...... I clean the scanner lamp and but nothing still linre in it can I open it and clean inside pleas help me thanks for all
If this occurs by using the ADF than likely there is crud on the slit glass.

what kind of line ???
1-black ?
2-white area through image or text area ? (White line in paper feed direction)
3-Digital Line ?
4- lines in both image and non image areas. ?
5-Lines on the copies only when copying from the Glass. ?
Clean and re-seat all the connectors to and from the Reader Controller,Inverter PCB and the Contact Image Sensor.
6-Lines on the copies only when copying from the DF. ?
**Knowledge is time consuming, exhausting and costly for a trained Tech.**

Thanks tecKat when I repleas cis the line desaper now how can clean cis can i open it and clean it inside please help me thank you
==================================!!! Can blower air ? usually never works !!
CIS---When detaching the contact sensor unit, take care not to touch the scanning lamp and the lens assembly.
-Scanning lamp used to illuminate originals.
-Rod lens array used to collect light reflected by originals.
-CCD array used to collect reflected light coming through a rod lens array.
-> receives light using a CCD array.
-> uses the CCD array to turn the light into an electrical signal (photo conversion), thus preparing output.
The machine's CCD array consists of 16 channels (units) in total. Each of these channels is equipped with an
output correction table, and generates image signals after gain correction on input intensity signals.
If any of the following occurs, be sure to execute the following service mode item to correct the output amongthe channels:
- there is a difference in the output of the image density among channels after replacement of the contact
image sensor (CIS).
- the CCD-LUT setting is not 0 after replacement of the reader controller PCB.
Service Mode:
- setting CIS unit gain correction data
COPIER>OPTION>BODY>CCD-LUT
- CCD Gain Fine Correction
COPIER>FUNCTION>CCD>LUT-ADJ2
(making adjustments using a D-10 chart)
After Replacing the CIS
Be sure to enter the values indicated on the CIS label attached to the contact image sensor (CIS) using the
following service mode items:
COPIER>ADJUST>CCD>CCDU-RG
(offset value against color displacement caused by CIS)
COPIER>ADJUST>CCD>MTF-MG
(MTF correction value for main scanning direction)
COPIER>ADJUST>CCD>MTF-SG
(MTF correction value for sub scanning direction)
Also, be sure to update the values indicated on the service label attached behind the reader left cover by
the values indicated on the CIS label.
Reference:
The machine is not shipped out of the factory with the CIS label attached to it.

thank you very much the old cis wich make lines can i clean it ? the new cis is work very good but
this one not main it my freand s photocopy and i must get it back to him
is ther any program or mode can solve this poroplem or it maybe just need clean help and thanks
