•

3.1 Spindle systems burning. This test will run for ½ hour, spindle in place, but no media 

loaded. 

•

If the test 3.2 or 3.3 were failing before the oiling and burn-in, re-run the test (3.2 and/or 3.3). 

•

1.3.4 OMAS Temperature Sensor 

•

1.3.5 OMAS Sensor Check, if there is any issue the system will report it. Ensure the OMAS internal 

and external temperatures match (this requires that the printer has been off for at least 1 hour).

•

Run the service check ‘4.3.4 Check roller Calibration’: 

1.

Load a roll of substrate with the following characteristics. 

- External diameter at least 140mm/5.5 inches 
- Remaining length at least 20m. 
- As wide as possible, ideally the full width of the printer. 
- The substrate type should be one for which the OMAS (Media advance) sensor works well, 

ideally a Self-adhesive Vinyl with a paper backing or any paper based substrate. 

2.

We recommend the following substrates: 

-

HP photorealistic (provided in the box with most of the new printers) 

- Avery MPI3000 of 78” (198 cm) wide. 

3.

However any substrate conforming to the characteristics described above can be used for this 

calibration. 

4.

Note: The printer will NOT actually print anything, but will advance around 14 meters of this 

substrate. 

5.

Before loading the substrate, clean the OMAS window (refer to the maintenance and trouble-

shooting guide). IMPORTANT: Before performing the calibration the printer must be ‘cold’, not 

having printed for at least one hour. 

6.

Load the substrate correctly according to the instructions from the support documentation, mea-

suring the distance between the side plate and the edge of the substrate in the input and output. 

7.

4. Select the appropriate substrate in the IPS. 

8.

5. Enter into the Service Menu (detailed process explained below), and select the following 

menu selections: 

•

4.3.4 Roller Calibration (total time 35 minutes, 10 meters of substrate advanced) 

•

4.3.5 Check Roller Calib (total time 10 minutes, 3.5 meters of substrate advanced) 

In case of an error code is displayed during this calibration, follow the information on the front 

panel, and contact your support representative. 

Exit from the Service Menu, and rewind all the substrate (using the substrate movement button, 

and pressing on the back key, the substrate will then rewind until the beginning of the roll). 

At the end of the Roller calibration and the Check Roller Calib, the main parameters of the 

calibration are displayed. If there is an error, the last line of the parameters will display an
