HCI jam detection

The HCI uses the following sensors to detect the presence of paper and to check whether paper is
being fed correctly or has jammed:
HCI media feed sensor (PS3301)
●
HCI right cassette media feed sensor (PS3302)
●
HCI left cassette media feed sensor (PS3305)
●
Figure 1-57

No pick jam 2

The HCI media feed sensor does not detect the leading edge of paper within a specified period from
when the HCI right cassette media feed sensor detects the leading edge.
The HCI media feed sensor does not detect the leading edge of paper within a specified period from
when the HCI left cassette media feed sensor detects the leading edge.

No pick jam 3

The HCI right cassette media feed sensor does not detect the leading edge of paper within a specified
period, including two times retry, from when the HCI right cassette pickup solenoid is turned on.
The HCI left cassette media feed sensor does not detect the leading edge of paper within a specified
period, including two times retry, from when the HCI left cassette pickup solenoid is turned on.
