HVPS = High Voltage Power Supply
I will attach two pictures with what I think it is defective in your printer. Take a look at the IBT motor drive gear
I did a panic stop while printing an 11x17 sheet and found that the defect was on the PRINTED sheet exiting the fuser but not on the unprinted sheet below the fuser. I could see the defect on the ibt belt below the fuser. I was not able to spin the ibt belt.
I also checked the other side of the machine where the belt cleaner assembly is and spun that around. There was a lot of magenta on the belt reflecting where the paper stopped as well as a line like the defect I've been having.
Please tell me what "hvps" is. I'm not familiar with the acronyms.
Thank you, I appreciate your input as well as everyone else's!
If is on all colors it is from IBT drive motor. Open the right cover of the machine an look inside at the gear of motor to see if one or more teeth of the gear are noy damaged.
Yes, David. All colors.
According to the chart, it should have been an imaging unit. I replaced all imaging units but the problem remains. Nothing changed.
The defect occurs in all colors.
Your issue is from magenta drum cartridge as Joe indicaing in that table (44mm - imaging unit).
Switch the image units (drums) between them to see if the issue is mooving too.
The Repeating Defects Page is a tool that can be used for troubleshooting print quality issues that have a consistent, repeating pattern.
The Repeating Defects Page is a tool that can be used for troubleshooting print quality issues that have a consistent, repeating pattern. For example, a smear that occurs every 44 mm / 1.7 in. down the page.
To determine the cause of the defect:
|Component||Repeating Distance (Metric)||Repeating Distance (Imperial)|
|Accumulator Belt||Every four pages of A4 or Letter size paper printed LEF, or on every other page of Tabloid size paper printer SEF.|
|Fuser||84 mm||3.3 in.|
|Fuser or Imaging Unit||94 mm||3.7 in.|
|Transfer Roller||88 mm||3.5 in.|
|Imaging Unit||44 mm||1.7 in.|
|Developer Roller||28.3 mm||1.1 in.|
NOTE: If it is determined that the Accumulator Belt or Developer Roller is the cause of the repeating defect, contact Support for additional assistance. All other components can be replaced without Service.
