HP Laserjet 4 Plus Driver Installation Procedures
These are general installation procedures for installing the HP Laserjet 4 Plus driver for a printer. If you are unable to make changes to your printer because of access or network limitations, please contact your network administrator or IT professional for assistance. 1. Go to Start Settings Printers.
Right-click over your printer and select Properties. Select the Advanced tab.

Click on New Driver. 1

Click Next.
Select HP for manufacturer and highlight HP Laserjet 4 Plus. Sometimes there may be variations of the HP Laserjet 4 Plus driver. Select either HP Laserjet 4 Plus or HP Laserjet 4 Plus (Microsoft) when available.

Click on Finish

You have now installed the HP Laserjet 4 Plus printer driver.
8. Once the HP Laserjet 4 Plus driver is installed, you are ready to test. a) First set the check printer with the Laserjet 4 Plus driver installed as your default printer. b) Open MS Word or Wordpad. c) Type ~**1M~(8M~(s0p8h10v0s0b100T1234567890ABCD and highlight the string. For Windows 2000 or XP, change the font to Courier or Univers. For Times New Roman or NT, change to Times New Roman. d) Print. If everything is configured properly, you should see a sample of the MICR font on the page. If it looks like this:

instead of

then something is wrong. Make sure that the printer is using the HP Laserjet 4 Plus driver. Check to make sure you have the proper font selected for its respective Operating System. Sometimes you may need to delete and Add a New Printer again. If this is a network printer and there is a print server involved, follow the steps outlined above on the print server first. Once it is configured properly and the MS Word test runs successfully on the print server, the next step is to setup the individual check printing workstations with the same driver and font configurations. Run the MS Word tests to confirm that they are correctly configured as well. NOTE: If the printers have Jetdirect cards, it may be easier to setup local TCP/IP ports on each workstation and then print to the ipaddress. Thus, bypassing the print server. 9. Last step is to test a check.

Configuration 3-1

Using The Control Panel
(See Appendix B for LaserJet 5 information.)

Figure 3-1

Control Panel Keys
The control panel (see Figure 3-1) consists of eight keys, three indicator lights, and a 16-character display panel. The three indicator lights are described in Table 3-1. Control Panel Keys There are two rows of control panel keys. The upper row keys have one function each. The lower row keys have a second level of functions which are accessed by holding down [Shift]. Note that the alternate functions [Reset], [Continue], and [-] are coded the same color as [Shift]. Table 3-2 details both plain key functions and shift-key combinations.

Configuration 3-13

Resource Saving (HP LaserJet 4 Plus and 5 only)
Resource Saving gives the printer the ability to save certain entities such as permanent soft fonts, macros, symbol sets and user-defined graphics patterns when the printer changes personalities, resolutions or page protect modes. For example, if a user switches the LaserJet 4 printer from PCL mode to PostScript mode, all PCL soft fonts macros are lost. The HP LaserJet 4 Plus/4M Plus printer would not clear these entities from memory. When the user switches back to PCL from PostScript all of the PCL entities would still be resident in the HP LaserJet 4 Plus/4M Plus printer. Resource Saving can only be accessed when the printer has the PostScript language installed and a minimum memory configuration of 7 MB. If the printer has a duplexer option, the minimum amount of memory necessary to access Resource Saving is 13 MB. The Resource Saving configuration is located in the Memory Configuration Menu. Resource Saving can be set for three modes, AUTO (default), ON, and OFF. Auto configuration sets the Resource Saving for PCL and Postscript to a minimum value (400 KBytes) for each personality. Setting Resource Saving to ON allows the user to determine how much printer memory will be used for Resource Saving for the PCL personality and the Postscript personality. The memory can be allocated in 100 KBytes increments. For example, if the user sets the Resource Saving memory size to 200 KBytes, a total of 400 KBytes of memory will be assigned to Resource Saving. 200 KBytes of memory will be used for Postscript Resource Saving and 200 KBytes of memory will be used for PCL Resource Saving. Turning Resource Saving OFF disables the Resource Saving function and no memory is allocated to Resource Saving.

3-14 Configuration

I/O Buffering (HP LaserJet 4 Plus and 5 only)
I/O buffering allows the user to allocate printer memory to hold the job while it prints, freeing up the host system sooner, like a print spooler. The standard printer has approximately 10 KBytes of memory allocated to I/O buffering and an additional 100 KBytes of memory is assigned to I/O buffering for each 1 MByte of memory added to the printer. If the printer has a minimum of 6 MBytes of memory installed (12 MBytes of memory for a printer with a duplex option), the I/O buffer size can also be adjusted from the control panel. Three settings exist for the I/O buffer; AUTO (default), ON, and OFF. AUTO sets the printers I/O buffer to a minimum value that is determined by the total amount of memory that is resident in the printer. Setting I/O buffering to ON allows the user to set the I/O buffer size from the front panel. Setting the I/O buffering to OFF disables I/O buffering. Note When you change the I/O buffer setting all downloaded resources are deleted.

Configuration 3-53

Caution
When removing a board from the antistatic package, avoid touching the metal traces on the SIMM board.
For memory boards, compare the part number on the outside of the package to the part number in the table below.

4-4 Preventive Maintenance

Toner Cartridge

The toner cartridge in your printer contains the printing mechanism and a supply of toner. Your toner cartridge life depends on the amount of toner your jobs require. When you print word-processed text, a toner cartridge lasts approximately 6,800 pages, printed at 5% coverage. (A typical business letter, as shown in Figure 4-2, is about 5% coverage.) This assumes that the print density setting is in the middle range (set to 3 in your printers control panel).

5-28 Functional Overview

Printing from the MP Tray (Tray 1)
MP tray selection is provided by the Formatter PCA, as configured by the operators control panel or by a software application. The MP tray (Tray 1) feed systems paper motion begins when the DC Controller PCA, after receiving a PRNT signal, starts the Scanner Motor (M5) and the Main Motor (M1). When the fusing roller reaches the minimum operating temperature (183 C), the MP pickup roller clutch solenoid (SL2) is energized for 1 second, allowing the MP pickup roller to make one rotation. Clutches and solenoids work together to start and stop gears and rollers used for paper movement. The MP pickup roller then feeds a sheet of paper from the MP tray (Tray 1). The Formatter PCA sends the VDO signal to the print engine within a specific time period after the paper reaches the Input/Registration Paper Sensor (PS1). This aligns the leading edge of the toner image on the photosensitive drum with the leading edge of the paper. After the paper passes the drum and the fusing rollers, it triggers the Paper Exit Sensor (PS3). The paper then is directed to the output tray. If the paper does not reach or clear each sensor within a specified time, the microprocessor on the DC Controller PCA assumes a paper jam occurred and informs the Formatter PCA.

Printing from the PC Tray (Tray 2)
PC tray selection is provided by the Formatter PCA, as configured by the control panel or by software. When the DC Controller PCA receives a PRNT signal, it starts the Scanner Motor (M5) and the Main Motor (M1). When the fusing roller reaches the minimum operating temperature (approximately 183 C), the PC tray (Tray 2) pickup roller clutch solenoid (SL1) is energized for 1 second, allowing the roller to make one rotation. The PC tray pickup roller then feeds a sheet of paper from the PC tray into the PC tray input feed rollers. The PC tray input feed rollers turn until paper reaches the Input/Registration Sensor (PS1). When the media is sensed at (PS1), the pickup motor (M2) stops and the paper is carried through the remainder of the print path by the Main Motor (M1). The Formatter PCA sends the VDO signal to the print engine after the paper reaches the Input Paper Sensor (PS1). This aligns the leading edge of the toner image on the photosensitive drum with the leading edge of the paper. After the paper passes the drum and the fusing rollers, it triggers the Paper Exit Sensor (PS3). The paper is then fed into the output tray. If the paper does not reach or clear each sensor within a specified time, the microprocessor on the DC Controller PCA assumes a paper jam occurred and informs the Formatter PCA.

Reseat all connectors in Lower Cassette. Replace the Lower Cassette Pickup Motor. Replace the Paper Control PCA. Replace the DC Controller.

7-24 Troubleshooting

14 NO EP CART Message
The printer detects the presence of the Toner Cartridge and the level of toner present in the cartridge through the condition of the ANTIN signal. The ANTIN signal becomes part of the serial data stream used to communicate with the DC Controller (see Figure 7-5 for cartridge components). Troubleshoot the 14 NO EP CART (or INSTALL TONER CARTRIDGE) message as follows:
1 Reseat the Toner Cartridge. Try a new or known good Toner

Cartridge.

2 Check the High Voltage Contacts for damage. If the contacts
are dirty or damaged, clean the contacts after the repair.
3 Replace the High Voltage Power Supply. 4 Check and reseat the HVPS cable. 5 Replace the DC Controller.

16 Toner Low Message

The TONER LOW message results as the level of toner in the cartridge cavity falls past the minimum level. The level is sensed by a mechanism similar to an antenna, which detects the AC Developer Bias Voltage applied to the developer mixture. If the TONER LOW message cannot be cleared by shaking or replacing the Toner Cartridge, perform the steps listed for troubleshooting the 14 NO EP CART message.

7-26 Troubleshooting

41.X ERROR Message
A 41.X ERROR (misprint) indicates that a temporary malfunction has occurred with the print engine (NOT a Formatter error). Occasional occurrences of this message can be expected. However, persistent 41 ERROR messages indicate a problem requiring attention. The 41.X ERROR is usually accompanied by a blank, or partially printed page. Pressing the [Continue] (or Go) key re-prints the page, and continues the print job. A 41 ERROR occurs due to the following conditions:
Incorrect Universal Tray Switch setting. Set the Universal
Tray and the Lower Cassette Tray paper size as shown in Chapter 3. Wrong size paper in tray. Check that the Universal Tray, and/or the Lower Cassette settings match the installed paper. An unstable or temporary loss of the Beam Detect pulse. This problem normally is accompanied by a partially printed page, often with thin horizontal black lines, deformed characters, or solid black areas. Loss of the Beam Detect pulse for more than 2 seconds results in a 51 ERROR condition. Paper reaching the Input Paper Sensor (PS1) before it is expected. This is accompanied by a blank page. This normally is due to paper feed problems. Proceed as directed in the following table.

DC Controller replaced. Paper Input Assembly replaced.
