Questions about HP developer units
What configuration is documented for the DV512 developer housing?
The DV512 developer housing is a new product with new carrier and an original sensor. Confirm the exact order configuration; sales must separately confirm price and availability.
What should I check if an HP 257 drum prints blurred output?
Compare whether the old drum shows the same blur. If it does, the machine, including its laser assembly, needs further checking. If the old drum prints normally, first check the new drum seating and consult technical support. Blur alone does not prove a specific fault or rule out a product defect.
Is an HC1994 drum interchangeable with HP drums?
HC1994 and HP chips differ and are not interchangeable. Confirm the version intended for HC1994. Contact sales for price and availability.
