#Recurrence check of the trouble

Check if the trouble the user claims recurs with the returned printer.

• If RIP was used, check if the trouble recurs when the driver is used.
• If 3rd party's media were used, check if the trouble recurs when a genuine medium is used.
• If 3rd party's ink was used, perform the repair according to the policy of each local sales subsidiary.
• If the F/W was not the latest, gain agreement with the user on the update of F/W, and check if the trouble recurs when the latest F/W is used.

#Check for the counter values/history

Download NVRAM and check the following with NVRAM Viewer. (For the check method, see "ADJUSTMENT")

• Counter history of the periodic replacement parts. (if any part's life is near.)
• Printer's operating history (if any cause for the trouble exists)
• Error history (the frequency/history of errors related with the trouble)

#Test print check

For the trouble related with print quality, carry out “Test Print” and check the current adjustment status. (For the procedure of test print, see "ADJUSTMENT")
