Replacement parts configuration
When the parts in the list below are replaced, specific tasks need to be performed. These
parts include:
● Formatter and DC Controller replaced at the same time
● Formatter (new and previously installed in another printer)
● DC Controller (new and previously installed in another printer)
● Media sensor (PS5)
● Color Misregistration Sensor (PS12)
● Laser Scanner Assembly
● Fuser
● Transfer unit (ITB assembly)
Configuration procedures for these parts are described in the following sections.
Formatter and DC Controller replaced at the same time
Do not replace both the formatter and the DC Controller at the same time. Replace one
at a time. If the formatter and DC Controller are replaced at the same time in an HP Color
LaserJet 3700 series printer that has the ability to perform duplex printing, this functionality
will be lost. To determine if the printer can duplex, print a configuration page from the
INFORMATION menu and reference Paper Trays and Options. If Duplex Unit is listed, the
printer is able to duplex and the formatter and DC Controller should be replaced one at a
time.
If the DC Controller and Formatter are replaced one at a time, then the duplex printing
capability will be transferred to the new DC controller or Formatter.
A printer specific PJL file will be needed to re-enable duplexing in the current printer (will not
work on any other printer), if both the formatter and DC Controller are replaced at the same
time. This file will only work in the current printer. Call for assistance from HP Support to
obtain the PJL file. Also, perform the Formatter and DC Controller replacement steps as
required below.
Formatter (New) replacement configuration
The values for Total Mono Pages, Total Color Pages, Serial Number, Service ID, Cold Reset
Paper (if needed), and the Fuser Kit Count will need to be reset using the service menu.
NOTE
The Transfer Kit count will be unaffected by the replacement of a formatter.
Print a configuration page and a supplies status page in the INFORMATION menu to obtain
the page counts, counts for any of the supplies, serial number, and the born-on date. If a
configuration page and a supplies status page cannot be printed, this information can be
obtained from the Service menu prior to replacing the formatter.
To ensure optimum print quality, the printer will need to be calibrated by performing 3
Calibrate Now's using the printer control panel by selecting CONFIGURE DEVICE / PRINT
QUALITY / CALIBRATE NOW.
