hi, I have a c284e which does not recognize A4 size when placed on the scanner glass. "Unable to detect original size" signal. The trick would be to set default to A4 and then the client can change. But I would like to understand if there is any calibration or check that I can do to fix the problem.

Re: A4 recognition from glass bizhub c284e
if the scanner is not bent, theres no scratches in the original glass at the detection area, the mirrors are clean, the non image area erase has been performed and the angle switch at the back side of the scanner is working you are probably looking at a failing ccd. Unless someone has seriously screwed around with the original glass scanner position adjustments.
Make sure the scanner lamp is illuminating the original just before the adf is closed as this is when the original size is looked at by the stationary scanner to measure the width. Long originals are by the 2 optical sensors over to the right. -
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: A4 recognition from glass bizhub c284e
hmmm.
I couldn't find the reference, but I did find this:
bizhub C224e, C284e, C364e, Zeus3MLK/ 2MLK/ 1MLK
"Original left on the glass." message when using DF. Off the glass LTR original size is detected as LGR, LTR-R originals are detected as LGL.
Faulty readings from original size detection sensor PS204. Sensor may have gotten wet. Salt stains on the PWB.
Monitor sensor state in Service Mode > State Confirmation > Sensor Check > pg 14 > original size detection 1 > 0: unblocked, 1: blocked. Adjust VR sensitivity until 0 output is achieved with glass installed, 1 output with paper present.

Re: A4 recognition from glass bizhub c284e
We may thinking of 2 different scenarios.
[Original left on glass.] is what you talk when using DF and [The original size cannot be detected. Select the paper size.] is another one when using copier glass.
Either ways I believe below are mentioned correct troubleshooting steps.

Re: A4 recognition from glass bizhub c284e
You can try to play around with <Original Size Detection> settings under <System1>.
Resolved issues like this before by simply toggling from Table1 to Table2 and then back to Table1 again.
Know it does not make sense but it worked before.
Some machines due to marketing areas have both the Sensor1 and Sensor2 installed.
Think Table2 is for fools cap.
If it has both sensors you can physically swap out the 2.WhateverComment

Re: A4 recognition from glass bizhub c284e
I was told that a slightly dirty glass plate might cause this issue, even if it looks ok. Try clean both sides properly if the other setting-related hints doesn't help.Comment

Told you it does not make any sense...
Glad it worked.WhateverComment
