    Re: I am getting "Clean Slit Glass" Error On a Canon Imagerunner 4225i

    OK, I preformed the System Registration, Preferences, Then Disply Message and I requested to have the clean slit Glass Message To "Off" However, I am now getting this message: :Original scanning area (thin glass strip) is dirty" I was wondering how do I change the values in the Service Mode. I understand to get into the Service Mode is * 2,8 Do I then select copier? and what do I do after that? Is the thin Glass Strips are they the strips of glass on the Exposure Carriage Assembly?

    You mean you didn't even try cleaning yet ?
    It's the thin glass strip (!) On you left when you open the scanner lid...

    Re: I am getting "Clean Slit Glass" Error On a Canon Imagerunner 4225i

    Yes,I did Clean the Glass and The Scan Slit Glass, I took the platen glass and the Slit glass off and cleaned the glass, scanning and the two glasses on the Exposure Carriage Unit. I done all of this and And now I am getting "Clean the Thin Glass Is Dirty" I am not an End-User I am a Technician whom can't understand why I am getting these messages after I clean the glass, scanning glass and two scan glass on the exposure system. Does anyone know the Service Mode in order to change the Dust settings? I know the code is *2,8 then do I select Copier? Then what area do i then going into?

    Are you getting lines on copy and scans? If so, you'll have to solve the issue. Maybe the glass is damaged or scrached ?
    Dirt on the scanner lid or roller underneatb may cause the msg also...

    Can't recall the setting to change the threshold, not by hart...

    Add..


    From service manual !!


    Service Mode




    (Lv1) COPIER > OPTION > IMG-RDR > DFDST-L1
    (used to adjust the dust detection level between sheets)
    (Lv1) COPIER > OPTION > IMG-RDR > DFDST-L2
    (used to adjust the dust detection level at the end of a job)




    Adjust these values to a lower number.Lowering the values reduces the circuit sensitivity.


    Adjustment rande 0-255
    Default 200
    Try with 100 or lower.
    Power cycle the machine for a value change to take effect.
