Toner cartridges, particularly for color laser printers such as the HP CP1215, are expensive. Thus, many users nowadays resort to toner refilling once these cartridges run out of toner supply. Refilling is the most sensible option, considering the cost ratio of toner to the entire cartridge unit which happens to be only 10% or even less than that. Toner supplied with a compatible HP CP1215 toner refill kit is retailed at $33.95 (package includes the reset chip) compared to the OEM cartridge which comes with a price tag of $80. So in a nutshell, the bulk of the amount paid by the user for a new OEM cartridge goes to the material and production cost of the polymer casing that is about $70 in the case of the HP CP1215 OEM cartridge. The user actually saves a lot of money if a cartridge can be refilled several more times over the recommended 3 to 4 refills.
What imaging components are found inside the HP CP1215 toner cartridge? The color cartridge comprises of the toner hopper and waste chamber duo, secured into place by end caps. Releasing the 2 vital components exposes the OPC drum, together with the wiper blade responsible for cleaning the drum’s surface of residual toner after each print cycle. The recovery blade completes the work of the wiper blade by channeling excess toner into the waste toner chamber. The second component is the Primary Charge Roller (PCR) that supplies the OPC Drum with a uniform negative DC voltage – a PCR function controlled by the laser printer’s intensity setting. Together with the doctor blade, PCR dictates the amount of charged toner that will adhere to the developer roller; aided in the process by the foam feed roller.

Any of the 3 rollers (OPC Drum, PCR and Developer Roller) would become the main cause of print defects if left to perform its routine functions indefinitely. Therefore, when pronounced print defects emanated from these vital components, the faulty component must be immediately replaced to sustain expected print quality. Nevertheless, attempt to analyze the cause of the print defect since print irregularities may also be triggered by a defective OPC Drum wiper blade or a dirty foam feed roller that are designed only as accessory to the main rollers, but can obviously cause backgrounding even then.
The OPC Drum has a rated capacity of over 30,000 printed pages at 5% coverage, so never suspect the integrity of the OPC, particularly when the capacity is not yet breached. Besides, an OPC drum has a microchip page counter that turns off the printer automatically once the rated capacity has been reached. In most instances, the PCR and developer roller are the first components to yield to the wear and tear of everyday laser printing, and following subsequent refills using HP toner refill kits. Therefore, the mentioned components need to be replaced as soon as possible to keep the toner cartridge in tip top condition.
So, when print defects persist and the OPC Drum is still in fine form, the user is left with no option but to replace the PCR and Developer Roller.
