Printer configurations
Below are the standard configurations for the HP LaserJet 1150 and 1300 series printers.

Printer drivers

A printer driver is the software component that provides access to printer features and provides the means for the computer to communicate with the printer. Choose a printer driver based on the way you use the printer.
Use the host-based printer driver to optimize performance. (HP LaserJet 1150 printer only). Use the PCL 5e printer driver if you need print results to look consistent with those from older HP LaserJet printers. Certain features are not available in this printer driver. (Do not use the PCL 5e driver for this printer with older printers.) Use the PCL 6 printer driver to take full advantage of the printer features. Unless complete backward compatibility with previous PCL drivers or older printers is necessary, the PCL 6 driver is recommended (HP LaserJet 1300 series only). Use the PS printer driver for compatibility with PostScript needs. Certain printer features are not available in this printer driver (HP LaserJet 1300 series only).
The printer automatically switches between PS and PCL printer languages depending on the driver you have selected.
Available printer drivers
The following printer drivers are included with the printer. Available printer drivers HP LaserJet 1150 printer

hp toolbox
You can view the HP toolbox when the printer is directly connected to your computer or when it is connected to a network. You must have performed a complete software installation to use the HP toolbox. The HP toolbox is a Web application that you can use for the following tasks:
Check the printer status. Configure the printer settings. View troubleshooting information. View online documentation.
See Using the hp toolbox for more information.
Embedded Web server (hp LaserJet 1300 series only)
The embedded Web server is available for HP LaserJet 1300 series printers with LIO network connections. With the embedded Web server, you can gain access to the printer settings and information by typing an IP address or hostname of the printer in a Web browser (such as Netscape NavigatorTM or Microsoft Internet Explorer) on any computer. You can use the embedded Web server to configure the printer, view status information, and obtain troubleshooting information. The embedded Web server works with the following supported web browsers:

Maintenance 47

Using HP print cartridges
HP policy on non-HP print cartridges
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either new, refilled, or remanufactured. Since they are not HP products, Hewlett-Packard cannot influence their design or control their quality. Service or repair that is required as a result of using non-HP print cartridges will not be covered under the printer warranty. Note The warranty does not apply to defects resulting from software, interfacing, or parts not supplied by Hewlett-Packard.

48 Chapter 4

Storing print cartridges
Do not remove the print cartridge from its package until you are ready to use it. The shelf life of a print cartridge in an unopened package is approximately 2.5 years. The shelf life of a print cartridge in an opened package is approximately 6 months. CAUTION To prevent damage to the print cartridge, minimize its exposure to direct light.
Storing print cartridges 49
Print cartridge life expectancy
The life of the print cartridge depends on the amount of toner that your print jobs require. When printing text at 5 percent coverage, the print cartridge lasts for the following average amounts:
HP LaserJet 1150 printer: 2,500 pages HP LaserJet 1300 series printer: 2,500 pages (a replacement cartridge that lasts for 4,000 pages is also available)
This life expectancy assumes that you set the print density to 3 and turn EconoMode off. (These are the default settings.)

50 Chapter 4

Saving toner
While in EconoMode, the printer uses less toner on each page. Selecting this option will extend the life of the print cartridge and reduce your cost per page, but it will reduce print quality. See Using EconoMode (Saves toner) for more information.

Saving toner 51

Redistributing toner
When toner is low, faded or light areas appear on the printed page. You might be able to temporarily improve print quality by redistributing the toner, which means that you might be able to finish the current print job before replacing the print cartridge. Note You will feel some resistance when you open the print cartridge door. Opening the print cartridge door conveniently lifts the print cartridge for removal. 1 Open the print cartridge door, and remove the print cartridge from the printer.
To prevent damage, do not expose the print cartridge to light. Cover it with a sheet of paper. 2 To redistribute the toner, gently shake the print cartridge from side to side.
If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold water. Hot water sets toner into the fabric. 3 Reinsert the print cartridge into the printer, and close the print cartridge door.

If the print is still light, install a new print cartridge. See Changing the print cartridge for instructions.

52 Chapter 4

Changing the print cartridge
Note You will feel some resistance when you open the print cartridge door. Opening the print cartridge door conveniently lifts the print cartridge for removal. 1 Open the print cartridge door, and remove the old print cartridge. See the recycling information inside the print cartridge box.
To prevent damage, do not expose the print cartridge to light. Cover it with a piece of paper. 2 Remove the new print cartridge from the packaging, and gently shake it from side to side to distribute the toner evenly inside the cartridge.
Bend the tab on the right side of the cartridge to break it loose.
Changing the print cartridge 53
Pull the tab until all the tape is removed from the cartridge. Put the tab in the print cartridge box to return for recycling.
Insert the print cartridge in the printer, making sure that the print cartridge is in position. Close the print cartridge door.
If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold water. Hot water sets toner into the fabric.

54 Chapter 4

Cleaning the printer
Clean the outside of the printer with a clean, damp cloth when necessary. CAUTION Do not use ammonia-based cleaners on or around the printer. During the printing process, paper, toner, and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems, such as toner specks or smearing. To correct and prevent these types of problems, you can clean the print cartridge area and the printer media path.
Cleaning the print cartridge area
You do not need to clean the print cartridge area often. However, cleaning this area can improve the quality of your printed sheets. WARNING! Before cleaning the printer, turn the printer off by unplugging the power cord, and wait for the printer to cool. 1 Open the print cartridge door, and remove the print cartridge.
To prevent damage, do not expose the print cartridge to light. Cover the print cartridge if necessary. Also, do not touch the black sponge transfer roller inside the printer. By doing so, you can damage the printer. 2 With a dry, lint-free cloth, wipe any residue from the media path area and the print cartridge cavity.

Cleaning the printer 55

Replace the print cartridge, and close the print cartridge door.
Plug the power cord back into the printer.
Cleaning the printer media path
If you are experiencing toner specks or dots on the printouts, clean the printer media path. This process uses a transparency to remove dust and toner from the media path. Do not use bond or rough paper.
For best results use a sheet of transparency. If you do not have any transparencies, you can use copier grade media (18 to 24 lb. or 70 to 90 g/m2) with a smooth surface. 3 Make sure that the printer is idle and the Ready light is on. Load the media in the input tray. Print a cleaning page using one of the following methods: Access the HP toolbox. See Using the hp toolbox for instructions. Click the Troubleshooting tab, and click Print Quality Tools. Select the cleaning page. Or On the printer control panel, press and hold the Go button until all three lights come on (about 10 seconds). When all three lights come on, release the Go button.

This page allows you to designate up to two e-mail addresses to notify of printer status alerts. Follow the instructions on the screen to set up e-mail alerts.

Administrative settings

This page allows you to set the frequency of how often the HP toolbox checks for printer alerts. Three settings are available:
once per minute (every 60 seconds) twice per minute (every 30 seconds) twenty times per minute (every 3 seconds)
If you want to reduce network I/O traffic, reduce the frequency that the printer checks for alerts.

Print cartridge information
The print cartridge is designed to simplify replacement of the major consumable parts. The print cartridge contains the printing mechanism and a supply of toner. At five percent page coverage, the standard print cartridge for the HP LaserJet 1150 and 1300 printers will print approximately 2,500 pages. The actual page yield obtained by a customer depends upon factors such as the percentage of coverage on the pages printed, toner density setting, EconoMode, and environmental conditions (temperature and humidity).
Print cartridge date stamp
Some HP LaserJet print cartridge packages are stamped with an alphanumeric date code. This code represents a 30-month period beyond the date of production in order to facilitate efficient inventory

management processes between HP and its resellers. It does not serve as an indication of toner life or relate in any way to warranty terms and conditions.
Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons: Repairs resulting from the use of refilled print cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. Hewlett-Packard has no control or process to ensure that a refilled print cartridge functions at the high level of reliability of a new HP LaserJet print cartridge. Hewlett-Packard also cannot predict the long term reliability effect on the printer from using different toner formulations found in refilled cartridges. The print quality of HP LaserJet print cartridges influences the customers perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled print cartridge.
HP LaserJet printing supplies
In many countries/regions, this products printing supplies (such as print cartridge, drum, and fuser) can be returned to Hewlett-Packard through the HP printing supplies returns and recycling program. This easy-to-use, free takeback program is available in over 48 countries/regions. Multilingual program information and instructions are included in every new HP print cartridge and consumables package.

Errors 153

Solving paper-feed problems
Use the following table to solve problems related to moving paper or documents through the printer. Table 19. Solving paper-feed problems Problem
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. Paper is curled or wrinkled when using the paper output bin.
Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet printer family.
Open the straight-through output door on the back of the printer and use this paper path. Reset the fuser mode to the default. Whenever possible, store paper in its sealed ream at room temperature. Use the long media extension. Select Optimize for: in the Paper tab of the printer driver. Make sure that it is set for the appropriate media. Remove some of the media. Be sure to center the paper with the side media guides. Verify that the guides are not adjusted too tightly or too loosely against the paper. Check for broken or missing guides and replace as necessary. Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet printer family.
Paper is not stored properly. The media is too long for the printer output bin. The fuser temperature is too high.
Print is misaligned on the page (skewed pages).
The main input tray is overfilled. The paper guides are not set correctly, are broken, or are missing.
The papers weight or surface finish does not meet HPs specifications.
154 Chapter 6 - Troubleshooting
Table 19. Solving paper-feed problems (continued) Problem
The printer feeds multiple sheets or jams frequently from the main input tray or priority input tray.
The paper guides are not adjusted properly.
Slide the guides against the sides of the stack in the main input tray or the priority input tray to center the paper. Make sure the guides are not adjusted too tightly. Always remove paper from the main input tray before refilling it. Remove some of the sheets. The main input tray can hold up to 250 sheets of 20-lb (75 g75 g/m2) bond weight paper (less for heavier paper) or from 20 to 30 envelopes. Remove some of the sheets. The priority input tray can hold up to ten sheets of 20-lb (75 g/m2) bond weight paper (one sheet of heavier paper) or one envelope. Break the ream of paper by curving it into an upside-down u-shape; this can effectively decrease multifeeds. Also try turning the paper around to feed the opposite end first, or use a different type of paper. Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet printer family. Do not allow more than 125 sheets of 20-lb (75 g/m2) bond weight paper (less for heavier paper) to fill the paper output bin. Clean the pickup roller. (See Cleaning the printer pickup roller on page 49.) Replace the pickup roller. (See Replacing the printer pickup roller on page 39.) Clean the separation pad. (See Cleaning the printer separation pad on page 50.) Replace the separation pad. (See Replacing the printer separation pad on page 42.) Check the sensors to make sure that none of them are jammed. If a sensor cannot be unjammed, replace the sensor.

160 Chapter 6 - Troubleshooting
To check the high-voltage connector assembly
The assembly uses three spring-loaded wire pins to contact the print cartridge: drum ground (callout 1), charging (callout 2), and developing roller (callout 3). Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty, clean them using isopropyl alcohol only. If they are damaged, replace the high voltage connector assembly.

Paper path check

If paper is not being picked up or is not moving through the paper path, you might want to observe all of the paper motion activities. Overriding the door interlock (SW301) allows you to observe: motor rotation solenoid action kick plate motion paper pickup roller motion drive roller, transfer roller, fuser roller and gear, and delivery roller motion

To override SW301

Figure 87.
Overriding SW4 Remove the left side cover. (See Left side cover on page 81.) Install the print cartridge, which will press SW301. Press the laser/scanner interlock switch (callout 1) on the laser/ scanner. While SW301 and the laser/scanner interlock are engaged, perform an engine test or self-test to observe paper motion. (See procedures elsewhere in this chapter.)

Service mode functions

NVRAM initialization
CAUTION Only perform the following procedure if absolutely necessary. Performing an NVRAM initialization resets some parameters that cannot be restored later. NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable. It also performs a system reset. NVRAM initialization resets the following: all menu settings to factory default values factory settings such as formatter number, page counts, and factory paper settings
To perform NVRAM initialization
3 Turn the printer off. Press and hold down the GO button. Turn the printer on, and continue to hold the GO button for at least 20 seconds. During this process, the GO button, Attention, and Ready LEDs will each turn on. Release the GO button. The printer LEDs will begin cycling. The NVRAM-unit process will run until the printer is in the ready state.
Service mode functions 163

Cold reset

A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike NVRAM inititialization, a cold reset does not reset the page count, the paper tray sizes, language, or formatter number. Note If an HP Jetdirect card is installed, remove it before performing a cold reset. Otherwise, the procedure will also reset all the HP Jetdirect settings as well as the printer settings.

To perform a cold reset

3 Turn the printer off. Press and hold down the GO button. Turn the printer on, and continue to hold the GO button for at least 5 seconds, but not longer than 15 seconds. During this process, the Attention LED will turn on. Release the GO button.

4 Note

If both the Attention and the Ready LEDs turn on before you release the GO button, you must start the procedure again with step 1. 5 The printers LEDs will begin cycling. The cold-reset process will run until completion, and the printer will return to the ready state.

182 Chapter 7 - Parts and diagrams
How to use the parts lists and diagrams
The figures in this chapter illustrate the major subassemblies in the printer and their component parts. A table (material list) follows each 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 fieldreplaceable units and cannot be ordered. While looking for a part number, pay careful attention to the voltage listed in the description column to make sure that the part number selected is for the correct printer model.
