Why Ricoh fax180 Fax Machine is printing black copies?
Your Ricoh Fax Machine might be printing black copies due to several reasons. It could be that the harness connected to the FCU is out of position; in this case, check the connection between the FCU (CN6) and the contact image sensor. Another cause might be a defective contact image sensor, thermal head, or FCU, which would require replacing the respective component.
What to do if my Ricoh Fax Machine is printing blank copies?
If your Ricoh Fax Machine is producing blank copies, the issue could stem from a few potential causes. The harness connected to the FCU might be out of position, so check the connection between the FCU (CN13) and the thermal head. Also, the thermal head or the platen roller might not be in the correct position, so verify their placement. If these checks don't resolve the problem, the thermal head or the FCU might be defective, requiring replacement.
Why does my Ricoh fax180 produce faint copies?
Faint copies from your Ricoh Fax Machine can arise from several factors. The exposure glass might be dirty, requiring a cleaning. Alternatively, the scan threshold might be set incorrectly, so you should adjust the scan threshold settings using Function 10-2. A defect in the contact image sensor (LED, sensor element) or incorrect positioning of the thermal head or platen roller could also be responsible. In such cases, consider replacing the image sensor and checking the position of the thermal head and platen roller.
How to fix uneven image density on Ricoh Fax Machine?
Uneven image density on your Ricoh Fax Machine can be caused by a dirty exposure glass, which requires cleaning. Alternatively, the contact image sensor may be broken and need replacement. The thermal head or the platen roller might not be in the correct position, so you should check if they are correctly placed. A defective thermal head may also be the cause and should be replaced if necessary.
Why Ricoh fax180 Fax Machine prints vertical black lines?
Vertical black lines on copies from your Ricoh Fax Machine can be due to several reasons. The contact image sensor element(s) may be defective, requiring replacement of the contact image sensor. There might be dirt or dust on the exposure glass, so cleaning it is recommended. The thermal head could also be defective, necessitating its replacement. Lastly, the paper in the machine might be scratched, so check the paper path for any damage.
How to resolve dirty background issue on Ricoh fax180?
If your Ricoh Fax Machine produces copies with a dirty background, it may be due to a scanner shading correction error or a wrong threshold. To resolve this, clean the exposure glass of the image sensor. You can also adjust the scanner contrast threshold settings using Function 10-2.
How to fix black dots or spots on Ricoh fax180 Fax Machine copies?
If you're seeing black dots or spots on copies from your Ricoh Fax Machine, it could be due to dust on the exposure glass, so clean the exposure glass of the image sensor. It may also be caused by a scanner shading correction error or wrong threshold; in that case, adjust the scanner contrast threshold settings using Function 10-2. Finally, the FCU may be defective, and replacing it might solve the issue.
What causes horizontal black lines on Ricoh fax180?
Horizontal black lines appearing on copies from your Ricoh Fax Machine can be attributed to a defective thermal head or a defective FCU. Consider replacing the thermal head or the FCU to resolve this issue.
How to eliminate white spots in black image areas on Ricoh fax180?
White spots appearing in black image areas on your Ricoh Fax Machine copies can be caused by dust on the exposure glass. Clean the exposure glass of the image sensor. It may also be due to a scanner shading correction error or wrong threshold. Adjust the scanner contrast threshold settings using Function 10-2. The FCU could also be defective, requiring replacement.
Why does my Ricoh fax180 produce vertical white lines?
Vertical white lines on copies from your Ricoh Fax Machine can indicate defective image sensor element(s), a defective thermal head, or a defective FCU. Replacing the image sensor, thermal head, or FCU, respectively, may resolve the issue.
