Formatter PCA
Special consideration
WARNING! Do not install a replacement formatter PCA and DC controller PCA at the same time, and
then turn the product power on.
The formatter PCA and the DC controller PCA store important product configuration information
(NVRAM data) that will be lost if both PCAs are replaced at the same time. When the product power is
turned on, the DC controller will restore the NVRAM data on the replacement formatter.
Replacing both the formatter and the DC controller at the same time will result in severe print-quality
problems.
Replacing the formatter PCA before the DC controller PCA
Use the following procedure if you need to install a replacement formatter PCA and a replacement DC
controller.
NOTE: If you are only installing a replacement formatter PCA, proceed to Remove the formatter PCA
on page 134.
1. Install a replacement formatter PCA.
2. Turn the product power on, and wait for the print-cartridge volume indicators to appear on the
control-panel display.
NOTE: This allows important product information to be written to the replacement formatter PCA.
3. Turn the product power off.
4. Install a replacement DC controller. See
Remove the DC controller PCA on page 131.
5. Turn the product power on.
Remove the formatter PCA
The formatter PCA shown in this procedure is for the HP Color LaserJet CP1510 Series Printer.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must make sure that all FFCs are fully seated in their
connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when
removing product parts. Always perform service work at an ESD-protected workstation or mat. If an ESD
workstation or mat is not available, ground yourself by touching the sheet-metal chassis before touching
an ESD-sensitive part.
1. Remove the right cover. See Right cover on page 103.
