Interpret 10 tap test results (OOBE states)
1. The printed tap test results contain a sequence of numbers at line number 68, "Startup Complete," of the printed report.
2. Use the following table and gure to interpret these numbers.
Column Code Acceptable values
Column 1 DSID_PEN_PRINTER_STARTUP_BITS A value of 1 indicates that the printbar has been started up.
This means that shipping uid 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_COMPLETE 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 1 means that pen height and beam center have been completed, and that
BDD is scheduled (or pending) to perform normally.
Column 6 DSID_BDD_FAIL_MASK 0–internal use only.
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.
