THEORY OF OPERATION
Printer Paper Path
Internal Duplex: Models T652 & T654
NOTE:
Duplex on the T652 or the T654 is not
a field installable option. In order for a model
T652 or a model T654 to have duplex capability, it must be ordered that way initially.
On rare occasions you may encounter a simplex T652x or T654x that has had the
duplex option disabled at the factory to satisfy a customer’s requirement. In this
situation, the duplex hardware has not been removed. The disabling action is not
reversible in the field.

For Training Purposes Only 6/3/2009
7
Duplex: Models T650
Duplex is a field installable option for model T650 only. It is functionally the same
theory of operation & uses the same basic paper path as did the T64x series printers.

Print Engine Transport System
Paper Tray Components
New spring-loaded side guide that enhances feeding & imaging consistency.
This left side guide helps prevent paper skewing. The spring loaded guide positions itself
to the nearest setting, allowing for imprecise setting of guides.
Doesn’t have to be reset with every ream. It allows a little forgiveness for
aggressive paper loading.
T65x Paper drawer holds 550 instead of 500. This allows a customer to load a full ream of paper prior to
totally emptying the drawer.
Multiple Sheet Feed Prevention
Media occasionally sticks together along the edges when loaded in the Tray. This may cause a multiple
sheet feed or paper jam. Wider restraint pads (on bottom of tray) help with bottom of tray multi-feeds.
Textured Ramps – use the same principals as our
Special Media Tray, causing fewer multi-feeds.
The T65x paper trays have several enhanced
features:
The back guide is easier to move.
There is a rear guide locking system that
ensures consistent sensing & behavior of
the media. It won’t get knocked out of
position. Ships locked according to geo.

Electrophotographic Process
Charge:
The twin charge rollers deposit a uniform negative electrostatic charge on the light-sensitive
surface of the photoconductor drum: (also called the PC, Photodeveloper, or OPC).
Exposure:
The printhead generates Laser light that enters the cartridge and strikes the photoconductor
(PC) drum in areas to be developed, forming an invisible (latent) electrostatic image of the
desired print. Note: Any form of light (laser, LED's, sun light, etc.) activates the
Electrophotographic (EP) properties of the drum coating. Consequently, care should be taken to
cover the PC when removed from the printer to protect it from exposure to a light source.
Development:
(Developer Roll) Toner is transferred from the reservoir in the toner cartridge to the
photoconductor drum through electrostatic attraction making the image visible on the PC drum.
Toner is attracted only to areas where the laser imaged the drum. Since the toner and the charge
applied to the drum are both negative, the toner will be repelled from areas where the laser did
not image the drum.
Transfer:
The transfer roll rolls along the underside of the paper to be imaged, and moves the toned
image from the photoconductor to the paper. The toner is negatively charged and the transfer roll
bathes the paper with a positive charge; this attracts the toner to the paper.
Fusing:
The paper – now with a “toned” image – moves through the fuser assembly. Using temperature
and pressure, it marries toner to paper.
Cleaning:
Waste toner (toner that was not transferred), paper debris and dust are removed from the
photoconductor drum by the cleaning blade.

Printheads [Oscillating vs. Spinning Polygon Mirror]
You need to be aware that there are differences in these two types of printheads. Both the alignment
procedures for each type of printhead, as well as the basic diagnostic
steps are different. This printhead
has an alignment procedure that is shown in the next section.
T650 & T650n
The T650 & T650n use an oscillating printhead and uses bidirectional printing. This printhead has a
tuning step in addition to the alignment procedure during installation.
T652dn & T654dn
The T652dn & T654dn use a spinning polygon mirror printhead, as did the T64x. This printhead is 40%
larger than the oscillating printhead and uses unidirectional printing. This printhead has an alignment
procedure that is shown in the next section.

Polygon & Oscillating printhead assembly adjustment
Do the printhead mechanically registration adjustment whenever you remove or replace the printhead or
loosen the mounting screws.
Install the new printhead with the mounting screws centered in the slots in the printhead frame assembly.
Leave the screws loose enough to allow the printhead to move from side to side within the slots. It is
necessary to perform a mechanical registration adjustment before locking down the three printhead
mounting screws.
In case of paper feed skew, go to “Alignment assembly – skew adjustment” [Page 15]
To perform the mechanical registration adjustment of the printhead:
1. Turn the printer off.
2. Press and hold
and to enter the diagnostic mode.
3. Turn the printer on, and release the buttons when Performing Self Test displays.
4. Select Registration from the menu.
5. Select Quick Test Page. The test page should only be printed on letter or A4 paper from Tray 1. The
Quick Test Page consists of alignment diamonds, horizontal lines that can be used for mechanical
registration adjustment. An example of the printhead alignment printout is shown below:
