In the same way that you can determine if the Printer is causing failures in
the Printheads, you can determine if the customer is replacing the
Printheads before the minimum life expectancy has
been reached without performing the maximum recovery action (Troubleshooting
procedure).
If the user replaces the Printhead without performing
a recovery action, the Printhead will be marked 0. If the user replaces
the Printhead after only performing Levels 1 or
Level 2 recovery action, the Printhead will be marked 1
or 2.
If a customer complains about having to replace the Printheads
frequently before the minimum life expectancy has
been reached due to poor print quality, using the information obtained
with the Printhead History Utility you can determine if the Customer
is replacing the Printheads too early as follows:
Enter the Printhead History Utility and Select the color of the
Printhead that is experiencing the replacement problem. In the following
example, Printheads 2, 3 and 4 were removed too early:
In order to check if the maximum recovery process (Troubleshooting
procedure) was performed on each Printhead, select the Printhead
and press the Enter key.
As you can see in the above example, all the Printheads were removed
before the minimum life expectancy was reached
(Ink used is below 100%) and the maximum recovery action was
not performed (P/H cleaning code is 0,
1 or 2). Therefore the conclusion
is that the Printer is OK and the problem is that the customer is
replacing the Printheads too early. In this case advise the customer
to use the Troubleshooting procedure (refer to
»
Performing the Troubleshooting Procedure) to
determine if Printheads need replacing or not. Emphasize that performing
the Troubleshooting procedure could recover the
Printhead if it is printing badly, therefore the User wouldn't need
to buy new Printheads frequently.
