Image Output Terminal
The Image Output Terminal (IOT) is an integrated module consisting of the following major
components:
• Bypass tray 4
• 3TM adjustable trays (Trays 1 and 2)
• 3TM fixed-size tray (Tray 3)
• Power supply
• IME that includes
– Vertical transport
– Horizontal transport
– Registration / Preheat assembly
– Marking unit
– Printheads
– Ink loader
– Ink delivery system
– Drum and transfix roller
– Drum maintenance unit
– Print engine electronics
Bypass Tray 4
The bypass tray is located on the left side of the IME and accepts standard or specialty media.
The user can fold the bypass tray upward when not in use. Bypass tray capacity is 100 sheets.
Figure 6
Sensors in the bypass tray detect the presence and approximate size of input media. When
media is detected by the input sensor, the IME prompts the user, via the control panel display,
to confirm media characteristics. The IME estimates the cross-process width of the sheet in the
bypass tray when the side guide has been correctly positioned. The bypass tray guide position
is zoned, with each zone attributed with a default media size(s). For certain sizes, the default is
dependent on market region. The default media size is also associated with a collection of sim-
ilar sizes. The user will be allowed to select the default media size indicated by the bypass tray
guide position, or to select from the list of similar sizes and types.
If the user loads envelopes, the bypass tray will initially detect them as one of the standard
media. The user will then have to select the ‘envelope’ option, which will trigger the bypass tray
to default to one of the standard envelope types. If the user loads custom size media, the
bypass tray will initially detect it as one of the standard media. The user will then have to select
the ‘custom size’ option and enter the exact size of the custom media loaded.

Tray 1 and Tray 2
Figure 7 . Trays 1 and 2 are fully adjustable and many supported media sizes are detected via
automatic size sensing. The tray side guides feature detent positions at the supported media
sizes (refer to
GP 20 Paper and Media Size Specifications) for the guides to lock to. In between
these standard sizes, the guides will still lock in position via a ratchet / pawl feature to support
custom sized media.
