Stains On The Back Side Of Paper Or Uneven Density At Regular Interval (5.0Mm) Due To The Scraped Drive Shaft When Outputting An Image - Canon imagePRESS C10000VPSeries Troubleshooting Manual

Stains on the back side of paper or uneven density at regular
interval (5.0mm) due to the scraped drive shaft when outputting
an image
[Symptom]
In the machines prior to the countermeasure cut-in serial number in factory described below stain on the back side of the paper
or uneven density at regular interval (5.0 mm) [A] may occur when outputting the image.
[Cause]
In the transfer cleaner drive unit of the 2nd transfer cleaner assembly, the shaft is scraped due to the abrasion of the drive shaft
and the bearing [a]. This may cause operational failure of the fur brush of the 2nd transfer cleaner assembly and the 2nd transfer
belt drive failure, resulting in the above-mentioned symptom.
[Reference]
- There is a possibility that the symptom occurs in all the 4 shafts shown in the Figure [A], however, the scrape occurs most on
the shaft [1] for structural reasons.
- If the shaft is replaced by itself, prepare the new-type shafts to replace.
- The scraped shaft cannot be limited to 1 location, but other shafts may be scraped, Therefore, replacing the 4 shafts at the same
time is recommended.

- If the shaft is replaced by itself, it will take about one hour longer than the unit replacing work of the drive assembly.
- When the symptom occurs, chips of the drive shaft may be found in the lower part of the 2nd transfer cleaner assembly [b].
