IR 1133IF Colour Scanning - Banding Problem

[Guest]

Hi Guys,

This one is driving me mad... any help would be much appreciated.
The 1133 is producing "Bands" when scanning in colour, both from the plate and through the feeder.
B&W scanning is fine, normal printing and copying is fine (in B&W as its a B&W printer).

Its not a driver issue as the bands also appear when scanning locally to a memory stick.
Its running the latest firmware.

I have had the glass off to clean under the calibration strip but still no change.

I think it could well be a setting that has been reset/cleared by accident in the service menu so im hoping its something simple.
Please help...

Thanks.

Hi teckat,

Apologies for the late reply.
I dont know much about these, but its not an L1 on there. The unit is much cheaper.
Ive looked all around it and cannot find the reader model on the machine or in the specs.

Also regarding the full auto graduation instructions.... If it helps at all - In the:
[Additional Function]>[Common Settings]>

The only options available are:
Draw Auto Selection
Switch Paper Feed Method

And in the:
[Service Mode]>[Copier]>[Option]

The only options available are:
Body
User
Acc
Lcns-Tr
Lcns-Of


I appreciate any advice you can offer.

===========

could be an issue with the CIS --contact image sensor

is this issue in same location on all color scans ??

[fiftyatfour]

Re: IR 1133IF Colour Scanning - Banding Problem

Yes - Same location on all scans (Colour)
Come to think of it greyscale looks quite light as well (although no bands)
Im fairly sure that its an accidental service menu setting change as it worked fine before it was moved to another network.

get a trained tech on product if available

it's the CIS that separates the Color Scan > output between CIS channels>shading start point

in service mode do u have a SCAN TEST

[fiftyatfour]

Re: IR 1133IF Colour Scanning - Banding Problem

In Service Mode I have:

[Copier]
[Feeder]
[Fax]
[Test Mode]

In the Test Mode I have:
[Printer]
[Fax]

There doesnt appear to be a SCAN TEST in any of the above menus.

Re: IR 1133IF Colour Scanning - Banding Problem

teckat,

In a last gasp of desperation I just did this in Service Mode...

[COPIER]>[FUNCTION]>[CCD]>[CL-AGC]

And it has almost resolved the issue.....
The copy from the glass plate is much better and the scan from the feeder is showing lines, but at least I can scan from the glass plate now...

As you can see though, I seem to have "shortened" the scan by 2-3cm in doing this. Would you know how to set this back to full A4?
And I would think it is likely to be a sensor setting rather than a paper size selection?
Thank you.

===================

did u check your Service Label ??

U may need to put back the Label SETTINGS !!!!!!!!!!!!!!


automatic gain control (AGC)

• COPIER > FUNCTION > CCD > CL-AGC (CIS light intensity adjustment (color)).
• COPIER > FUNCTION > CCD > BW-AGC (CIS light intensity adjustment (B&W)).



do u see this setting at all >>>>>>>>>>>

MF5900/D1300 Series/ may be similar to your 1133iF ???
After replacing CIS units:
1) Check that there is no problem with the setting values written on the service label.
2) Close the ADF, and execute the following service mode. If it results in NG, execute it again after turning OFF and then ON the power.
• COPIER > FUNCTION > CCD > CL-AGC (CIS light intensity adjustment (color))
• COPIER > FUNCTION > CCD > BW-AGC (CIS light intensity adjustment (B&W))
3) After executing the following service mode (a), check the value automatically set with the following service mode (b), and write it in the service label.
(a) COPIER > FUNCTION > INSTALL > STRD-POS (executing automatic detection of the reading position at DF stream reading)
(b) COPIER > ADJUST > ADJ-XY > STRD-POS (adjusting the reading position at DF stream reading)
4) Place a blank paper on the Copyboard Glass, and execute white level adjustment in the following service mode.
• COPIER > FUNCTION > CCD > DF-WLVL1 (white level adjustment [copyboard scan])
• COPIER > FUNCTION > CCD > DF-WLVL3 (white level adjustment B&W [copyboard scan])
Next, place the same blank paper on the DF and execute the following service mode.
• COPIER > FUNCTION > CCD > DF-WLVL2 (white level adjustment [DF scan])
• COPIER > FUNCTION > CCD > DF-WLVL4 (white level adjustment B&W [DF scan])
If it results in NG, execute it again after turning OFF and then ON the power.

Re: IR 1133IF Colour Scanning - Banding Problem

Thanks teckat,

That seems to have done the trick.
Out of interest I cannot see a service label anywhere on the machine?
I take it, it should just be on the back somewhere..
Does the service label just contain the same defaults that are in the Service Manual?

The machine you mentioned (D1300 Series) does indeed seem identical to the 1133IF unit I have.

======================================

believe the Label may be on metal plate that covers Main Controller in back of printer (u need to remove printer back cover to view)
Label has factory tested settings for your printer & it may show the standard defaults also /

Very Important before u clear RCON or DCON U NEED TO
or hopefully they are still on label in printer- they default back to the Manual defaults after a CLEAR.

Think in your model u can use a USB to export/import the Main Controller pcb settings before/on replacement of it-

get a manual


Tested settings are used when u replace Boards, ADF unit, Reader unit & it's settings needed, CIS unit,Document Exposure / Feed System settings and many more

Backing up Service Mode
Each device is tuned at the time of shipment and the tuned values are written on the service label.

However, when replacing the main controller PCBs / DC controller PCBs or clearing RAM, tuned ADJUST and OPTION values are reset to defaults.
Each service technician should adjust these values in field and ensure to write values after changes in the service label. If the
corresponding item is not found on the service label, enter the value in the blank space.
