Level Adjustment Flag

Selects whether or not the copier determines that the original is A5/HLT size when the APS sensor does not detect the size.

If "A5 length/5.5" x 8.5" is selected, paper sizes that cannot be detected by the APS sensors are regarded as A5 lengthwise or 5.5" x 8.5". If "Not detected" is selected, "Cannot detect original size" will be displayed. Numbers 2 and 3 are used for Chinese paper sizes (267 x 390 mm and 195 x 267 mm). The meanings of numbers 2 and 3 are the same as for number 1 and 2. However, if the APS sensors detect the original, the machine assumes Chinese paper sizes.

For example: A4 → 195 x 267 mm A3 → 267 x 390 mm

Displays whether or not the standard white level adjustment has been done.

Paper rolled up on the shift tray

QAC Field Information Dept.

Troubleshooting Mechanical Paper path Other ( )

Part information Electrical Transmit/receive

Prepared by:

Action required Service manual revision Retrofit information

M.Mimura

SYMPTOM

When a large number of sheets, such as thirty, are stapled in the multiple copy mode, a couple of the bottom sheets in the stapled stack may be rolled up on the shift tray.

CAUSE

If the paper facedown-curls excessively, the stapled set of paper will not slide back all the way to the extreme right position on the shift tray. If this happens, the lower leading edge of the next set may catch on the trailing edge of the set already on the tray, causing a couple of the bottom sheets to roll up.

This symptom could occur with a thick stapled set when the copies have piled up high on the tray. Heavy paper sets will generate stronger friction with the paper set underneath, and as the copies pile up, the angle of the top copies will level off and make sliding back more difficult.

Note

: 1. Non-staple mode copies will not exhibit this symptom because single sheets of

paper are delivered to the shift tray at a time.

2. Due to the nature of the copy job type in which this problem occurs, this symptom would more likely occur with heavy volume users such as copy shops, rather than with casual users.

SOLUTION

1 The copy paper has a characteristic that one side creates more curl than the other

side. Therefore, instruct the customer to flip over the paper in the paper tray to reduce the amount of paper curl. For those customers who have a wide selection of paper brands, recommending a paper brand which creates less curl might be more beneficial for the customer. (See page 23 of the Copy Reference manual for related remarks.)

2 This symptom may occur more with A4/11” x 8.5” sideways feed. This is because the

paper can slide up the tray further than other paper sizes. (Larger sizes of paper will not go that far because of the friction with the lower set of copies.)

If that is the case, install the new version ROM (#A6815103E). The new version ROM decreases the exit speed of A4/11” x 8.5” sideways paper to drop the paper close to the right frame for easy switch back. (This happens for stapling more than 11 sheets.)
