How to Install Premium Compatibles HP 640A C4195A Imaging Drum Unit

• Install the new drum — Align the drum unit with the printer’s bay and slide it in until it seats firmly. Ensure any latches or locking mechanisms engage securely. Reinstall toner cartridges if they were removed, and double-check that all components are properly seated.
• Run a test print and calibration — Close the access panel and power the printer back on. Print a user test page or alignment page to verify image quality, alignment, and toner coverage. If any adjustments are needed, follow the printer’s guidance for alignment or calibration until the output is consistent and sharp.
