Image-formation system
Pickup, feed and delivery system
Accessory
The printer routes all high-level processes through the formatter, which stores font information, processes the
print image, and communicates with the host computer.
The basic printer operation comprises the following systems:
● The engine-control system, which includes the high-voltage and low-voltage power supplies (HVPS and
LVPS), fuser control circuits, and the DC controller printed circuit assembly (PCA)
● The laser/scanner system, which forms the latent image on the photosensitive drum
● The image-formation system, which transfers a toner image onto the paper
● The pickup, feed and delivery system, which uses a system of rollers and belts to transport the paper
thro
ugh the printer
● Optional accessories (paper feeder, paper decks, staple stacker multi-bin mailbox)

The DC controller controls the operation of the printer and its components. The DC controller starts the printer
operation when the printer power is turned on and the power supply sends DC voltage to the DC controller. After
the printer enters the standby period, the DC controller sends out various signals to operate motors, solenoids,
and other printer components based on the print command and image data that the host computer sends.

ENWW Engine-control system 7
Page 36
Motors
The printer has four motors. The motors drive the components in the paper-feed and image-formation systems.
The DC controller monitors the fuser motor and the drum motor to determine whether a motor has failed. It
noties the formatter when it encounters the following conditions:
● Startup failure: the motor does not reach a specied speed within a specied time from when the motor
starts.
● Rotational failure: the rotational speed of the motor is not in the specied range for a specied time after
the motor reaches a specied speed.

Fans
The printer has four fans for preventing the temperature from rising in the printer and for cooling the printed
pages.
The DC controller determines whether there is a fan failure and noties the formatter if a fan locks for a specied
time from when the fan starts.

The low-voltage power supply (LVPS) circuit converts the AC power from the wall receptacle into the DC voltage
that the printer components use.
Figure 1-4 Low-voltage power supply circuits
12 Chapter 1 Theory of operation ENWW
Page 41
Low-voltage power supply voltages description
The low-voltage power supply converts the AC power into two DC voltages, which it then subdivides, as
described in the following table:
Table 1-10 Converted DC voltages
Main DC voltage Sub-voltage Behavior
+24V +24VA0 Stopped during active OFF or inactive OFF
+24VA2 Stopped during active OFF or inactive OFF
+24VB Stopped during active OFF or inactive OFF

+3.3V +3.3VA Stopped during inactive OFF
+3.3VB2 Stopped during inactive OFF
+3.3VC Stopped during active OFF or inactive OFF
=3.3VF Stopped during active OFF or inactive OFF
Over-current/over-voltage protection
The low-voltage power supply automatically stops supplying the DC voltage to the printer components
whenever it detects excessive current or abnormal voltage. The low-voltage power supply has a protective
circuit against over-current and over-voltage to prevent failures in the power supply circuit.
CAUTION: If DC voltage is not being supplied from the low-voltage power supply, the protective function might
be running. In this case, turn the power switch o and unplug the power cord.
Supplied intermittently during active OFF
Do not turn the power switch on until the root cause is found and corrected.
If the protective function is active, the DC controller noties the formatter of a low-voltage power supply failure.
In addition, the low-voltage power supply has two fuses to protect against over-current. If over-current ows
into the AC line, the fuse stops the AC power.
Safety
For personal safety, the printer interrupts +24VB and +24VC power when the cartridge door detection switch is
turned o. This stops DC power supply to the high-voltage power supply (HVPS)
ENWW Engine-control system 13
Page 42
The printer also stops the +24VB power when the +24V interlock switch is turned o. This stops DC power
supply to the following load:
● High-voltage power supply
● Drum motor
● Fuser motor
● Duplex switchback clutch (duplex models)
The remote switch control circuit turns on or
power switch is turned o. Unplug the printer power cord before disassembling the printer.

Fuser heater protection is a feature that detects excessive temperatures in the fuser and interrupts the power
supply to the fuser heater.
The following three protective components prevent the fuser heater from excessive rising temperature:
● DC controller: When a thermistor or sub-thermistor detects a temperature above a certain threshold, the
DC controller interrupts power to the fuser heater.
● Fuser-heater safety circuit: The fuser heater safety circuit monitors the detected temperature of the
thermistors and interrupts power to the fuser heater when it detects excessive temperature.
● Temperature fuse: When the fuser heater reaches a temperature above a certain threshold, the
temperature fuse interrupts power to the fuser heater.

DC controller
The laser/scanner system forms the latent electrostatic image on the photosensitive drum inside the toner
cartridge.
The DC controller receives instructions from the formatter regarding the image of the page to be printed. The DC
controller signals the lasers to emit light, and the laser beams pass through lenses and onto the scanner mirror,
which rotates at a constant speed. The mirror reects the beam onto the photosensitive drum in the pattern
required for the image, exposing the surface of the drum so it can receive toner.
The laser/scanner system consists of the following main components:
● Laser assembly
● Scanner motor assembly
● Beam detect (BD) sensor
● Scanner mirror

Memory chip
The memory chip is non-volatile memory that stores information about the usage of the toner cartridge and
helps protect the customer from counterfeit cartridges. This chip is also used to detect the presence of a
cartridge within the printer or when a cartridge is installed in the wrong slot. The printer reads and writes the
data in the memory chip.
Dynamic security
Certain HP printers use cartridges that have security chips or electronic circuitry. Cartridges using a non-HP chip
or modied or non-HP circuitry* might not work. And, those that work today might not work in the future.
As is standard in the printing business, HP has a process for authenticating cartridges. HP continues to use
security measures to protect the quality of our customer experience, maintain the integrity of our printing
systems, and protect our intellectual property. These measures include authentication methods that change
periodically and might prevent some third-party supplies from working now or in the future. HP printers and
original HP cartridges deliver the best quality, security and reliability. When cartridges are cloned or
counterfeited, the customer is exposed to quality and potential security risks, compromising the printing
experience.
* Non-HP chips and modied or non-HP electronic circuitry are not produced or validated by HP. HP cannot
guarantee that these chips or circuitry will work in your printer now or in the future. If you are using a nonoriginal HP cartridge, please check with your supplier to ensure your cartridge has an original HP security chip or
unmodied HP electronic circuitry.
JetIntelligence
JetIntelligence supports two features for managing toner cartridges.
● The authentication feature allows customers to specify the use of only genuine HP toner cartridges in the
printer.
● The anti-theft feature enables locking a cartridge to a specic printer or eet of printers.
Authentication
The genuine HP authentication feature allows a customer to specify that only genuine HP supplies can be used in

can be enabled or disabled from the control panel or the Embedded Web Server (EWS).
If a genuine HP toner cartridge from another printer is moved to a printer with this feature enabled, the toner
cartridge will authenticate and print, unless the toner cartridge has passed the low state. If the toner cartridge
has passed the low state, an Unauthorized Cartridge message displays on the control panel.
If a non-HP toner cartridge is used in a printer with this feature enabled, the message Unauthorized Cartridge
appears on the control-panel display.
NOTE: If a customer suspects they have a counterfeit cartridge, they should report it by going to

Pickup, feed, and delivery system
The DC controller controls the pickup, feed, and delivery system according to commands from the formatter. The
pickup, feed, and delivery system uses a series of rollers to move the paper through the printer.
The pickup, feed, and delivery system consists of the following three functional blocks. The DC controller
controls each block to pick up, feed, and deliver the paper.
● Pickup-and-feed block: Controls the movement of the paper from each pickup source to the fuser inlet
● Fuser-and-delivery block: Controls the movement of the paper from the fuser to the delivery destination
● Duplex block: Controls the movement of the paper from the duplex switchback unit to the duplex re-pickup
unit (duplex models
