how to retrieve meter counter manually from Asficio SP C431DN?
Elisavel A on Jul 17, 2015
BEST ANSWER: The page count or meter of most Ricoh networked devices can be obtained through the menu, by printing a report, or by browsing the printer's internal web page. For example, page 99 of the software manual for the SP C430DN and SP C431DN says,
1. Press the [Menu] key.
2. Press the [ ] or [ ] key to select [List/Test Print], and then press the [OK] key.
3. Press the [ ] or [ ] key to select [Config. Page], and then press the [OK] key.
I own this printer and need to replace the color PCU. I have found 2 different part numbers - 406663 and 407019. Are these the same items? Will either work as a replacement?
