In the field, when an image having a halftone area on the upper side of a solid image area was output under a low temperature environment, void appeared

along the border between those areas (in the halftone image side).

Field Remedy

1. In Service Mode > COPIER > Option > BODY > IMGC-ADJ, change the setting to '1'. (default: '0')

Reference: IMGC-ADJ is used to add/remove the image adjustment items, which are used by the system administrator, to/from the Additional Functions

Mode screen.

2. In Additional Functions Mode > System Settings > Device Management Settings > White Gap Correction, change the setting to '1' or '2', and then press OK.

3. In order to prevent a poor color balance that may be caused as a negative effect from Step.2, perform Auto Gradation Correction (Full Adjustment).

Reference: As a risk to output images, coarse image may occur.

14.3.1.4.6 Fingerprint

imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+

Symptom

In case of manual feeding for making a copy of half-tone image/solid color image, fingerprint symptom tends to occur.

Cause

Fingerprint left on the media at manual feeding appears in its image as a transfer failure after secondary transfer.

Remedy

Set the Service Mode (Delete fingerprint: COPIER > OPTION > USER > FINGM-SW) setting value as "1" and execute it.

Executing this Service Mode prevents the occurrence of fingerprint by performing fusing operation and normal print before printing image.

This service mode executes fusing operation twice, thus it takes longer time to make a copy than usual.
