Vertical lines on your Kyocera Ecosys M2035dn or P2135dn prints are a classic sign of a dirty or exhausted drum unit. These workhorse printers use the DK-170 (or DK-150/130) imaging assembly, which can eventually accumulate waste toner on the cleaning blade, resulting in those annoying black streaks.
In this guide, I will show you how to perform a deep clean of the drum unit or choose the correct replacement part to get your printer back to perfect condition.
Supported Models (DK-170 / DK-150 / DK-130)
This guide and the recommended parts are designed for this specific Kyocera generation:
- All-in-One Printers: ECOSYS M2035dn, M2535dn, FS-1035MFP, FS-1135MFP.
- Desktop Printers: ECOSYS P2135d, P2135dn, FS-1320D, FS-1370DN.
Step-by-Step Fix for Vertical Lines
- Remove the Drum Unit: Open the front cover and remove the combined toner and drum assembly. Separate the DK-170 unit.
- Inspect the Surface: Rotate the green drum cylinder carefully. Any line of toner you see on the drum will appear on your prints.
- Manual Cleaning: As shown in my video, you can disassemble the unit to clean the internal cleaning blade and the charge roller. This is the most effective way to remove Kyocera vertical lines without spending money on new parts.
- When to Replace: If the green coating of the drum is physically scratched or “peeled,” cleaning will not fix the issue. You will need a new DK-170 unit.

Common Issues & Troubleshooting
Vertical lines can also be caused by a dirty “corona wire” (the charger inside the drum unit). Use the built-in green slider on the drum unit to clean it several times before disassembling the whole unit.
