Purpose

This procedure provides a means of checking HFSI counters for paper feeding components and the Drum Cartridge CRU.

Procedure

Read out the HFSI counters using this procedure. Before beginning the procedure either print or copy Table 2 HFSI Items Fill In Table

Perform the following steps to read out the data for each counter:

1. Enter the Diagnostics Mode using GP 1.
2. At the chain prompt, enter the chain number (630).
3. Refer to Table 1 HFSI Items or Table 2 HFSI Items Fill In Table to find the link numbers for the counters. Start at the first entry in the table and proceed in consecutive order. Enter the link number of the item.
4. Press the Start button.
5. In the second row and second column of the table, record the two digit number that appears.
   NOTE: HFSI counters are listed as a series of two digit numbers. Enter “0 0” if the number is “0”. If the number is a single digit, enter the number into the table with a leading “0” as “0 (digit)”.
6. Press the Start button. The link prompt will appear.
7. Repeat Steps 3 to 6 and proceed with entering data into the table for each chain link code in Table 1 HFSI Items, in order from left to right, and top to bottom.
8. When the table is complete and the 12 Tray Counter cells are filled, you can read the HFSI counter values in each row from left to right as 8 digit numbers.
9. Press the AC button to return to the chain prompt.
10. Enter the chain number (633) for the remaining percentage of the CRU.
11. Press the Start button.
12. Enter the link number (004) for the remaining percentage of the CRU.
13. Press the Start button.
14. Record the number that appears in the UI Display, in the table of HFSI counter values as the “Drum Cartridge Remaining Percentage”.
