- Temperature/humidity of the installation site
- Drivers/RIP that the user uses
- Genuine media or 3rd party's media?
- Genuine ink or 3rd party's ink?
- F/W version (the latest?)
- Check also the following if necessary.
| Phenomenon | Check Item |
|---|---|
| Bad print quality | The installation site inclined? |
| Any vibrating equipment near the site? | |
| The user's panel settings | |
| Is the interior dirty? Clean it if dirty. |

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.
- 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)
