Evaluating the Diagnostic Stripe

The Diagnostic Stripe is an option that can be turned on in the Print Parameter menu. If 

the option is turned on, then on the first swath of printing a stripe is printed on the away 

side of the image. The stripe is printed every time the gantry has stepped approximately 

250mm. The stripe can yield a lot of information regarding the position and condition of 

the heads.

Each head has a row of 128 nozzles. The outer nozzles are not fired in the image or in 

the Diagnostic Stripe. Due to the nature of the head, adjacent nozzles can’t be fired at 

the same time. Nozzles are labeled in the following order:
Outer Nozzle A B C A B C ……….. A B C A B C Outer Nozzle
                 1 

  

  

  

  

  

  

 .………...

  

  

  

  

  

• •

  128

In the Diagnostic Stripe all the ‘A’ nozzles are fired first, then the ‘B’ nozzles and finally 

the ‘C’ nozzles. Each nozzle is fired 16 times. Refer to Figure 24 below.

Figure 24  Detail From Diagnostic Stripe

Note:

Make sure the media is large enough to allow the stripe to print on the away 
side.
