For the LaserJets 4 and 4M printers, Hewlett Packard recommends
the installation of a maintenance kit after every 150,000 pages
printed. This is a rough estimate and you may need to install a
maintenance kit far sooner than that depending on printing conditions
and if the printer has been previously serviced with low quality
aftermarket parts.
A picture is worth a thousand words...
It's a lot easier to show somebody how to install a maintenance kit than
to tell them. After talking with hundreds of customers over the phone
about installing printer maintenance kits we decided to write our own
manuals. The instructions we found from Hewlett Packard and other sources
were missing lots of information and often didn't contain any pictures.
So here you are! We hope you find the installation instructions helpful.
A lot of time went into creating them, feel free to email us with your
