Is This the Right Part?
| Vertical lines on printed pagesThin vertical lines running the length of the sheet are one of the most common signs the transfer belt cleaning blade has worn or become damaged. | Repeating marks down the pageMarks or defects that repeat at a regular interval down the page often point to a damaged section of the cleaning blade rather than the belt itself. |
| Grey background or toner hazeA cleaning blade that's no longer sealing properly lets toner residue build up on the belt, showing as a light grey cast or haze across the page. | Toner contamination or dirty printsScattered toner inside the printer, or dirty-looking prints, can mean the waste toner section of the blade assembly has failed or is no longer collecting toner correctly. |
| Not the fault?Print defects can have more than one cause. If cleaning or replacing this blade doesn't resolve the issue, contact us and we'll help you narrow down the next step. | |

What's Included
- 1 × Transfer Belt Cleaning Blade with integrated waste toner section (Z7Y78A) for HP Colour LaserJet Managed E87650 and E87660 series
- Blade only — this is not a complete transfer belt unit
Install Notes
- Power off and unplug the printer before opening any internal panels.
- Access the transfer belt assembly following your printer's service documentation — this varies by model, and the belt unit typically needs to be released before the cleaning blade section is accessible.
- Handle the transfer belt surface with care and avoid touching it directly — residual toner around the blade area is normal.
- Remove the old blade/waste toner section and fit the replacement, checking orientation matches the original before reassembling.
- Reassemble and run several test prints to confirm the defect has cleared.
This part sits inside the transfer belt assembly. If you're not comfortable accessing this area, we'd recommend having it fitted by an engineer — contact us if you'd like guidance before starting.
