And the Warranty status is not filled in, but the verification of in/out Warranty is pretty easy to check 

(current date < expiration date and cartridge not empty and issue with the cartridge). 

Note that Matte black is marked, while there is no other black. Do not take into account the ‘Matte’, this 

is mainly coming from other Designjet printers, where we have to distinguish 2 or even 3 different blacks. 

•

More information from the ISM (ink pressure sensor current values & calibration values, status of 

each cartridge, status of the ink electro valve, intermediate tank current level and counter (number of 

cycles), air pressure values and status of air relieve valve).

Which values we should expect if the printer is working well: 

•

Pressure sensor level: should be at least 1000 - 1500 mpsi unless there is no cartridge or one empty 

cartridge.

•

Pressure sensor calibration values: should match versus what is marked on the ink pressure board.

•

Intermediate tanks ink level: when weighing the intermediate tank, should be similar when weighing 

by hand the intermediate tank.

•

Air pressure sensor: in case the printer pressurizes the ink system (for example, after a job is just 

done), the value should be around 5000-5500mpsi (on one side only, not on both).

•

Information about the PPS/Scan beam: The current status can have the following values: HOMING, 

LOW, HIGH, HIGH_PRINT, MEDIA_LOAD, UNKNOWN, HALT. 
In case of high or high_print: the printer can print with the scan bean at a high position, increasing 

the level of spray…There is now an easy way to check remotely the scan beam position!!! 

In case of ‘unknown’, the scan beam has to be recovered (will try to move to the homing position). 

More information available in the training.
