The appearance of a gray background or “haze” on printouts is one of the most common problems with the new generation of HP JetIntelligence printers. Usually, users blame the toner cartridge, but in 90% of cases, the culprit is a dirty or worn-out imaging drum. In this guide, we will show you how to professionally clean and recycle the HP 32A (CF232A) and HP 19A (CF219A) drum units.
These modules utilize a specific “cleanerless” technology (no cleaning blade), making their maintenance significantly different from standard cartridges.

Drum Unit Compatibility
The procedure shown in the video is identical for the two main types of HP JetIntelligence imaging drums:
- HP 32A (CF232A): Used in HP LaserJet Pro M203, MFP M227fdw, and M227sdn models.
- HP 19A (CF219A): Used in HP LaserJet Pro M102, MFP M130a, M130nw, M130fn, and M130fw models.
Step-by-Step: Restoring Print Quality
Since these modules do not have a cleaning blade, the primary responsibility for image clarity falls on the PCR (Primary Charge Roller) and the OPC Drum.
- Disassembling the Module: Carefully release the side clips without breaking them. For more tips on handling delicate plastic components, see our Kyocera fuser repair guide.
- Cleaning the PCR Roller: This is the most critical step. Use a soft cloth and isopropyl alcohol to remove accumulated toner dust. A dirty PCR is the main cause of the gray background.
- Inspecting the OPC Drum: Check the surface for scratches. If there are visible marks, cleaning won’t help, and you will need to replace the cylinder. This process is similar to our DK-1150 drum maintenance guide.
- Cleaning Internal Contacts: Ensure all electrical contacts are free from toner to guarantee proper charging of the rollers.
- Reassembly and Testing: After cleaning all elements, reassemble the unit and run a test copy to verify the fix.
