1. General information
The Lexmark 3300 Series (4479-XXX) All-In-One features an electromechanical color scanner, copier, and printer that creates characters and graphics by composing programmed patterns of ink dots using a printhead and liquid ink. The printhead uses small heater plates and nozzles to control ink flow and the formation of characters on the print media. The printhead assembly and ink supply are combined into a single-unit print cartridge available as a customer replaceable supply item. Dual printheads provide color and true black printing without changing printheads. The number and size of inkjets or nozzles in the printhead determines the overall quality and capability of the printer. The black print cartridge has a total of 640 nozzles and installs on the left. The color cartridge has a total of 480 nozzles installs on the right. The photo cartridge has a total of 480 nozzles and installs on the left. The All-In-One is capable of printing in two directions from either cartridge.

Control panel
The control panel is set up to function in scan and copy mode. The LCD offers different options depending upon the mode.

Buttons Power

Functions The Power button turns the power on and off when the All-In-One is idle. When the All-In-One is on and performing a standalone or computer based print job, pressing the Power button cancels the print job and sends a printer initiated cancel print alert to the computer. The All-In-One will power off after the page has been ejected. During a computer scan job, this button cancels the job by sending a scan abort command to the computer. During a computer copy job, this button performs a combination command, to cancel the print and scan job. During a standalone copy job, this button cancels the copy job and ejects the page.

Maintenance station service check

The maintenance station has three functions: 1. Wipes (cleans) the printhead nozzle plates 2. Provides a place for printheads to fire all nozzles, keeping them clear for printing 3. Seals the printheads when they are not being used to prevent the nozzles from drying FRU Maintenance Station Assembly Action As the carrier moves to the left over the maintenance station, a slot on the bottom of the carrier engages a tab on the sled of the maintenance station, causing the cap to rise and seal the printheads. When the carrier moves to the right, it uncaps the printheads. The wipers clean the printhead nozzle plates as the carrier leaves the maintenance station. The wipers clean the printheads only when the carrier is moving to the right. After the cleaning operation is complete, a tab on the maintenance station engages a tab on the carrier, causing the wipers to lower. Worn wipers can cause poor print quality after printhead cleaning. Check for loose or worn wipers. Worn caps cause the printhead nozzles to dry and clog. Check for loose or worn caps.

4. Repair information
This chapter explains how to make adjustments to the All-In-One and how to remove defective parts. Warning: Read the following before handling electronic parts.

Handling ESD-sensitive parts

Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing system board:

Keep the ESD-sensitive part in its original shipping container (a special

ESD bag) until you are ready to install the part into the machine.

Make as few movements as possible with your body to prevent an

increase of static electricity from clothing fibers, carpets, and furniture.

Put the ESD wrist strap on your wrist. Connect the wrist band to the
system ground point. This discharges any static electricity in your body to the machine. Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If you are removing a pluggable module, use the correct tool. Do not place the ESD-sensitive part on the machine cover or on a metal table; if you need to put down the ESD-sensitive part for any reason, first put it into its special bag. Machine covers and metal tables are electrical grounds. They increase the risk of damage because they make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharge paths without being grounded.) Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install machine covers when you are not working on the machine, and do not put unprotected ESD-sensitive parts on a table. If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case). Be extra careful in working with ESD-sensitive parts when coldweather heating is used, because low humidity increases static electricity.

Removal procedures
The following procedures are arranged according to the name of the All-In-One part discussed. CAUTION: Unplug the power cord before removing any parts.

Releasing plastic latches

Many of the parts are held in place with plastic latches. The latches break easily; release them carefully. To remove such parts, press the hook end of the latch away from the part to which it is latched.

4-2 Service Manual

4479-XXX

Removals
General precautions on removals
Use caution when disassembling and reassembling components. The close proximity of cables to moving parts makes proper routing a must. When components are removed or replaced, any cables disturbed must be replaced as closely as possible to their original positions. Before removing any component from the machine, be sure you note the cable routing. When servicing the machine:

Verify that documents are not stored in memory. Move the print cartridge to the far right to cap the nozzles. Unplug the power cord. Use a flat and clean surface. Use only authorized replacement parts. Do not force plastic parts.
