Remanufacturing the HP Color LaserJet 2500
Released back in October 2002, the HP Color LaserJet 2500
was Hewlett-Packard’s first entry into the low-cost color printer
market. At a starting price of just under $1000 ($999 to be
exact), it was the cheapest color printer HP ever released–well,
at least for a few months.
In 2003,
ers.These host-based printers rely on the host computer to render the print jobs before it is sent to the printer. What does this
mean for the consumer? How about a savings of about $450!!
The HP1500L has a list price of only $549.99, making it the least
expensive color printer ever released by HP. The reason HP can
sell the printer so cheaply is because the computer handles the
processing of the print job. This means the printer requires
less memory and processor power, which leads to a lower cost
printer. The HP 1500L requires only a 150MHz processor
and 16MBs of RAM, while the HP 2500L requires a 300MHz
processor and 64MBs of RAM.
In June 2004, HP discontinued the HP2500 line of printers and
released the new HP Color LaserJet 2550.Capable of printing 20
monochrome pages per minute, that’s 4 pages faster than the
HP2500. However the color print speed remained the same,
only 4 pages per minute.
HP released the HP1500 and the HP1500L color print-
The new Canon engine uses five consumables, four toner
cartridges and one imaging unit. There are different part
numbers for the HP2550 consumables. Further testing is needed to determine if changes have been made to the cartridges.
he color cartridges for the HP 1500 and HP 2500 series print-
T
ers (C9701A Cyan, C9702A Yellow and C9703A Magenta) print
4,000 pages at 5% coverage, while the black toner cartridge
(C9700A) yields 5,000 pages at 5% coverage.The black cartridge
for the HP 2550 series printers (Q3960A) also prints 5,000 pages
at 5% coverage.The color cartridges however are available in a
high yield version (Q3964A Cyan, Q3962A Yellow and Q3963A
Magenta) that yield 4,000 pages at 5% coverage,as well as a low
yield version (Q3971A Cyan, Q3972A Yellow and Q3973A
Magenta) that yield only 2,000 pages at 5% coverage.
The imaging units consist of the OPC drum and a transfer
belt. Both imaging units yield the same amount of pages:
20,000 monochrome and 5,000 pages full color. However, the
part numbers are different. The HP 1500 and 2500 series printers use part number C9704A and the HP 2550 series uses part
number Q3964A.
