Solenoid sensors and switches

The following figure shows the locations of the solenoid, sensors, and switches. 46 Chapter 4 Operational overview ENWW Solenoid, photosensors, and switches 1 Door switch detects whether or not the print cartridge door is closed. Printing cannot continue until the print cartridge door is closed. 3 Paper-width sensor senses the width of the paper. 4 Paper delivery sensor senses when paper has successfully moved out of the fusing area. 5 Top-of-page sensor detects the leading and trailing edges...

Engine control system engine control unit and power assembly

The engine control system coordinates all print engine activities. The engine control system includes both the engine control unit (ECU) PCA and the engine power assembly PCA. In other HP LaserJet products, the ECU and power functions are combined onto one PCA known as the controller PCA or the DC controller PCA. In the HP LaserJet 1010 series, the control functions are primarily relegated to the ECU PCA and the power functions to the engine power assembly PCA. The ECU controls the following...

How to use the parts lists and diagrams

The figures in this chapter illustrate the major subassemblies in the product. A table follows the exploded assembly diagram. Each table lists the reference designator, the associated part number for the item, and a description of the part. Parts that have no reference designator or part number are not field-replaceable units and cannot be ordered. Failure of a part that is not listed as replaceable and is not included with a listed field-replaceable unit requires replacement of the entire...

Printer paper feed system

The main input tray and the priority input tray merge into one main input area. The printer senses the paper as it enters the paper feed path via the top of page sensor (PS801). It does not sense the presence of media prior to beginning the print cycle. The following steps occur when the product receives a print job The ECU activates the motor (M1). Paper motion begins when the ECU energizes the pick-up solenoid (SL1). The paper pickup roller rotates once. The paper lift plate pushes the media...

Solving print paperfeed problems

Solving print paper-feed problems Table 6-3. Solving print paper-feed problems Pages are coming out curled or wrinkled. Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to heat. Paper curl tends to relax as the paper cools while resting on a flat surface. Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet family. Reset the fuser mode to the default. Whenever possible, store paper in its sealed...
