WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before
attempting to service the product. If this warning is not followed, severe injury can result, in addition to
damage to the product. The power must be on for certain functional checks during problem solving.
However, the power supply should be disconnected during parts removal.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Many repair operations will require you to flatten or straighten flex cables. However,
where possible, try to avoid doing so. You

NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
Throughout this chapter, the reinstallation process should follow the reverse order of the removal
process documented. Where necessary, the tasks include reinstallation tips to aid in the installation of

10 tap test results (OOBE states)
The printed tap test results contain a sequence of numbers at line number 68, "Startup Complete," of
the printed report.
Use the following table to interpret these numbers.
Table 1-1 10 tap test results, row 68
Column Code Acceptable values
Column 1 DSID_PEN_PRINTER_STARTUP_BITS A value of 1 indicates that the printbar has been started up.
Access the Engineering menu on page 14.
This means that shipping fluid has been removed from the
printbar and replaced with ink. This is the expected state for a
printer after initialization.
Column 2 DSID_OOBE_STATE 255–OOBE messaging complete.
Column 3 DSID_INK_SUPPLY_OOBE_COMPELTE 1–SHF purge is complete and service wipes have been
enabled.
Column 4 DSID_CAL_OOBE_STATE A value of 2 means that the OOBE printed calibrations are
complete.
A value of 1 means the OOBE printed calibrations are in
progress
A value of 0 means the OOBE printed calibration does not
exist so no printing/calibration for OOBE is attempted.
Column 5 DSID_IQ_LIST_INDEX A value of 3 means that pen height and beam center have
been completed, and that BDD is scheduled (or pending) to
perform normally.
NOTE: For 1315FR firmware and above.
Column 6 DSID_BDD_FAIL_MASK 0–internal use only.
16 Chapter 1 Removal and replacement ENWW
Table 1-1 10 tap test results, row 68 (continued)
Column Code Acceptable values
Column 7 DSID_IDS_FIRST_CHARGE_REQUIRED 0–internal use only.
Column 8 DSID_PRINTHEAD_CAL_NEEDED A value of 0 indicates that OOBE calibrations (not IQ
calibrations) are complete. This is so the messaging is complete
for the calibrations. For example, if this value is 0, but the
CAL_OOBE_STATE=1, you will get the printed OOBE
calibrations, but the control panel may display Preparing
instead of Calibrating.
