Product History and Service Notes

Known Problems in the Last Firmware Revision A.02.10

This problem will be solved in the following firmware releases.

D None of the HP JetDirect EX cards work with the DesignJet 755CM in a MAC

environment.

Solution

D Install firmware revision A.02.10 (pn C3195Ć60135).
D Verify if the mark encoder has a black line or a notch in the middle. This is needed to

optimize the performance of the paper advance calibration. In case this line or the notch

is not present, you should install it (Refer to Service Note ' page 10Ć18). The following

units were shipped without the mark (even though some of them were reworked in the

Distribution Centers).

Serial Numbers:

C3195A ESA0000000/ESA5B05350

C3196A ESA0000000/ESA5B20304

C3198A ESA0000000/ESA5B02306

D Perform the accuracy calibration (details ' page 7Ć6) when you are upgrading from

firmware revision A.02.08 or lower. To get the best performance use HP Matte Film

media.
