Process Control Self-Check: SP3821
After the process control self-check is executed manually with SP3820, you can
execute SP3821 to check the results of the self-check. The possible error codes are
listed in the "Displayed Code" column in the table below.
When you do SP3821, the normal display (no errors) will look like this:
10101010
Reading from left to right each "10" represents a color: K, M, C, Y.
If a problem occurs, the code will appear in the column for the color PCU where the
error has occurred. For example, If a Vdhome error (Code 15) (see table below)
occurs in the M PCU, the display will look like this:
10151010
Or if an ID sensor error (Code 21) (see table below) occurs in the Y PCU:
10101021
NOTE: "99" displays while SP3821 executes.
Important: Noise and static electricity can damage the many sensors that are used
during the process control self-check. Because of this, always turn the machine off
before doing any procedure described below that requires disassembly.
