♦ Clean Head

When white lines are appeared, when image is printed poorly in part, sweep the nozzle of the ink cartridge and contacting surface of the cartridge, then clean the cartridge. Until it gets better, do it several times. On the inkjet print system, the print quality can be degraded by several causes , and the main root cause among the causes will be from the head.If the print quality is not good, the user should do this process to get a good print quality . This operation can be initiated from the printer dri ver menu or Maintenance menu from the control panel of the product. When the operation is initiated , the diagonal patterns and purge patterns are printed out. The first diagonal pattern is to indicate the current nozzle status before cleaning. The 3 purge patterns are operations for cleaning cartridge.This operation includes purging , wiping and spitting. The second diagonal pattern is to indicate the current nozzle status after cleaning.

♦ Align Head

Using this feature to get fine print quality when a vertical line is printed not in straight or when ink cartridge is just replaced.

♦ View Ink Level

To check the amount of the mounted ink cartridge. The product has no ink level monitor sensor. Therefore the firmware counts ink dot whenever the ink is fired , and we call it as ink level monitor gauge. This is not automatic method , so the user should do proper operation whenever the user installs the new ink head. The firmware will record the ink dot count be fired into the backup information memory whenever the printing job is finished and the machine is in idle state. The user can monitor the current ink level on the Maintenance menu. The level will be displayed as like x/8 and this value indicates the remained ink level. If the current ink level reaches to 1/8 , the firmware will display 'Install new cartridge'. message to indicate current remained ink can be exhausted soon . This message will be displayed continuously unless the ink is replaced and the user selects the New Ink. Under Ink Low state , the received fax message will not be printed out unless the user replaces the ink and selects the New Ink. But , PC printing and copy job will be done under this Ink low condition.

♦ Adjust Scanner(see page 4.8)

Use this adjustment feature to achieve best image (scan) quality depending on the characteristics of the CIS (Contact Image Sensor) parts. Use this feature to correct the reference of the CIS if you experience bad copy images. When using this feature, a white paper should be used to get clean copy images.

1. Select [Adjust Scanner] in Service mode

2. Press

'Start/Enter'(A message “Load white paper docu-

ment and press Start/Enter”

is displayed on LCD)

3. Place the empty white paper (Letter size) in a Feeding unit.

4. The original is scanned when press 'Start/Enter' button.

5. After finish the scan, a message is displayed on LCD and the ìAdjust scanner profileî is outputted.

6. If the outputted image is different to the normal image, a CIS is inferiority.

Caution :

1. Always perform Adjust Scanner after replacing the CIS.

2. Always use a clean white paper in Adjust Scanner (Maximum paper width: Letter Size).

3. Adjust Scanner may be performed even in the User Mode but Adjust Scanner profile is output only in the TECH MODE.

<Reference> The CIS type scanner needs scanner adjustment operation to get a good scanning quality. This is called as Shading Compensation . All kinds of scanner use light have a distortion according to component tolerance. This tolerance can make a distorted scan signal. To cover this problem , the firmware has a reference scan waveform into the non-volatile memory for each CIS . This reference waveform will be made in the factory when producing the product. But , the scanner , CIS , characteristics can be changed as it is used therefore the scanning quality can be different with first time. At this time , the user should initiate this operation from the control panel menu using white document. Then the old reference waveform will be replaced with new reference waveform for current CIS characteristics. This function can be initiated in Maintenance menu. When the new shading waveform is generated , the waveform will be stored into a Flash memory sector , and the checksum value is calculated and stored also. Whenever the scanning job is initiated , the checksum value is re-calculated and compared with stored checksum value. If the value is different , the Firmware regards as the shading waveform be stored into Flash memory is broken due to unknown reason and will display the message to indicate retrying Adjusting Scanner operation before the scanning job.

♦ Self Test (see page 4.11)

It is possible to check whether a machine works properly or not. ROM Version/Connect Telephone Line/Shading area checksum check/Modem check/Cartridge check, etc.

♦ ASF Test

The function is to test the function of ASF (AUT O SHEET FEEDER), and it is needed in the production progress. Service person doesn't need to use it.

♦ Modem Test

Use this feature to hear various transmission signals to the telephone line from the modem and to check the modem. If no transmission signal sound is heard, it means that the modem part of the main board is poor.

♦ DTMF Test

DTMF (Dual Tone Multi Frequency) signal. When you press any key on the number keypad including • and #, you will hear the corresponding key tone.

4.3.34 The Printer is Not Working (2)- Only SF-331P

• Description

While the power is turned on, the printer is not working at all by the PRINT command from the computer.

Check and Cause Solution

1. Perform the Printer Self-Test. (See page 4.9)

2. Check if the PC and the printer cable are properly connected.

3. Check if the printer driver is correctly installed.

1. Check the power source of the printer first and perform the Printer Self-Test. If the test results in printing, it is considered as there is no problem in the printer itself. If the printer is not working, the function may be defective (not due to S/W), so take another proper measure.

2. Check the status of the printer connection, and if it is defective, replace the printer cable (USB).

3. Check the connection between PC and printer port (USB port). Check if the printer driver at the Printers on the Control Panel is installed. If the printer driver is properly setup, check in which program the printing is not working. The best way is to try printing from the Wordpad, the WINDOWS basic program. Sometimes, the print out is normal within the WINDOWS basic programs, but it may not work in a specific program. In such case, reinstall the printer driver.

• Description Even after the Print command, there is no response at all or the printing speed is low.

Check and Cause Solution

It may due to wrong setup of the environment rather than malfunction of the printer itself. And in case that abnormal characters are printed out, also check the environment setup.

1. Secure the hard disk space.

2. Printing error occurs even if there is enough space in the hard disk.

3. Reboot the system, and try printing again.

1. Not working with the message 'Insufficient memory' means that the hard disk space to store the print information is insufficient rather than the RAM insufficiency. In this case, secure more space for the hard disk. Secure more space for C drive by using the Disk utilities program at 'PROGRAM - ACCESSORIES - SYSTEM TOOL' from the Start menu.

2. The connection of the cable or printer port is not properly setup.

3. If characters are printed abnormally, the cable or the printer driver may be defective. Turn the PC and printer off, and reboot the system to try printing again. If the problem still exists, double click to install the printer from My Computer and right-click the mouse, then click 'Test Print' button at the bottom of the file information tab. If normal characters are not printed again, the cable must be defective so replace the cable with a new one.

• Description

The printing is not working properly even when the cable has no problem. (even after the cable is replaced) If the printer won't work at all or strange characters are only printed, it may be the printer driver problem.

Check and Cause Solution

1. Printer driver error.

2. Error due to insufficient memory. (The printing job sometimes stops during proceeding or not completed due to insufficient memory.)

1. Check 'My Computer - Printers'. (If the printer driver is installed not compatible with the printer currently installed or an error occurs in the driver file, remove the existing driver and reinstall the printer driver.

2. This is because of an insufficient virtual memory. (It does not mean the actual capacity of RAM but the space of hard disk.)

Delete unnecessary files to secure enough space of the hard disk and try printing again.

4.4 Print Cartridge & Print Quality

4.4.1 Print Cartridge Maintenance

The top of the carriage contains a spring latch for the print cartridge. The spring latch provides tension for consistent snapin of the print cartridge. The print cartridge should only be replaced when the carriage is in the designated service position, which is controlled from the product’s front panel.

When installing a print cartridge, the bottom portion of the print cartridge should be installed into the carriage assembly as shown in Figure 1. Once the bottom is seated in the carriage, push the top portion of the cartridge toward the carriage until it snaps into place beneath the spring latch. Always ensure that the electrical contacts inside the carriage are clean. Do not handle or touch the contacts because oil from the user’s fingers can corrode the electrical contacts (see Figure in section b for carriage and cartridge contact cleaning instructions).

The service station, at the left end of the carriage path, contains two wipers and two nozzle caps to provide servicing and capping for either a monochrome or a color print cartridge (see Figure 2). The caps and wipers are mounted on a rotary assembly, which incorporates a micro-switch for accurate positioning.

The service station wipes and caps the orifice plate of the print cartridge after each print job and at predefined set points to ensure long product life. The orifice plate on the print cartridge is wiped to remove any excess ink, which could harden and cause the nozzles to clog. The print cartridge is then capped to prevent the ink nozzles from drying out. The cap vents into a rubber base through a vent line, so that all atmospheric interactions with the nozzles occur through the vent (see Table 1 in section 4.4.4.2 for cartridge life information).

4.4.2 Tool for Troubleshooting

The following tools are recommended for servicing and troubleshooting the Graphic Print Bar graphics print bar:

• Lint free swabs (cotton swabs are not recommended)

• Torx #’s T8 & T10 drivers

• Small flat head screwdrivers

• Needle-nose pliers

4.4.3 Print Quality

This section provides possible causes and solutions for print quality problems.

4.4.3.1 Poor Print Quality

Unacceptable print quality can include:

• Faded, faint, fuzzy, or smeared printout

• Inconsistent print density

• Missing dots or White Lines in Print (see section 4.4.3.2)

For print quality problems, check the following:

1. The print cartridge can cause print quality problems.

2. The paper can cause print quality problems. a. Verify that the paper meets the specifications of a high quality plain paper copier media for standard mono-

chrome printing. If color printing is being performed on a media suited only to text printing, the quality may be unacceptable. For high quality color printing, media that is designed for high-quality color inkjet printing is recommended. SEE MEDIA SPECIFICATION in Chapter 2: Specificatons

b. Some papers that meet the paper specifications may not provide acceptable print quality. Try a different

brand or type of paper.

c. Turn the stack of paper over and try printing on the other side of the paper. (Most papers have a recom-

mended print side, which is identified on the paper packaging. If print quality improves, no further troubleshooting is necessary.

Note : The Graphic Print Bar is designed to work well with most types of paper, although variables in

paper manufacturing and composition can significantly affect print quality and paper handling. Most paper manufactured for high-quality photocopying yields good results for general monochrome printing. For high density, high quality color printing, paper should be tested before large quantities are purchased, in order to ensure desirable performance.

SEE MEDIA SPECIFICATION in Chapter 2: Specificatons

3. Heavy concentrations of ink can cause the paper to buckle and produce smeared printouts. Try a different type

of paper specifically suited for inkjet printing which can absorb more ink when printing.

4. Ink from damp and buckled paper can leave excess ink on components in the paper path. Clean ink residue

from mechanism components if they are contaminated by wet ink.

5. Crusted ink on the print cartridge nozzles can cause smearing and missing dots

(see section 4.4.3.4 about cleaning crusted ink from the nozzles).

6. Damage to the encoder strip can cause print quality problems. Check for problems with the encoder strip and

spring. If necessary, replace affected parts.

Page 45

4.4.3.2 Missing Dots

If any rows of dots are missing on printouts (as shown in Figure3 ), check for the following problems:

1. The print cartridge may be past its expiration date, running out of ink, or faulty. If so, replace the print cartridge.

2. The print cartridge may not be making good electrical contact with the carriage assembly. Make sure that the print cartridge is seated and pressed securely against the carriage contacts. Remove and reinstall the print cartridge, making sure that the cartridge snaps into the carriage assembly, as shown in Figure 4.

3. The carriage contacts or print cartridge contacts may be dirty (see section 4.4.3.3 about cleaning the electrical contacts).

4. The print cartridge may have been stored uncapped and out of the mechanism, which can cause a severely dried out, clogged nozzle. (see section 4.4.3.4 about cleaning the orifice plate and print cartridge nozzles). If the ink cartridge is only missing a few dot rows, the cartridge may have a damaged or scratched nozzle. If the nozzle appears scratched or damaged in any way, replace the cartridge.

5. There may be a hardware problem. Check the following:

a. The flex circuit (between the carriage assembly and the logic PBA) may not be making good contact.

Reinstall the flex circuits into connectors on the logic PBA.

b. The carriage assembly may be faulty. Check for problems with the carriage assembly. If necessary , replace

the carriage drive system. Refer to the procedure in section.

4.4.3.3 Cleaning the Carriage Contacts and Cartridge Contacts

1. Use only lint-free swabs moistened with water. Do not use cotton swabs.

2. Clean the contacts as shown in Figure 5. Caution : Do not clean the print cartridge nozzles or orifice plate with swabs.

3. Let the contacts dry after cleaning.

4. Reinstall the print cartridge into the carriage assembly.

4.4.3.4 Cleaning Crusted Ink from Print Cartridge Nozzles

Storing an uncapped print cartridge outside of the service station can cause a crust of ink on the nozzles. Do not install an ink-crusted print cartridge into the product.

Caution : Use care during cleaning to avoid staining your hands or clothes with ink from the print cartridge.

1. Hold the print cartridge by the top of the cartridge.

2. Scrape dried ink off of the orifice plate into a trash container , using the edge of an index card or other rigid paper

stock (see Figure 6).

3. Follow the host printer’s instructions to initiate a printing self-test to produce a page of printed information.

• If dots are not missing toward the end of the printout, the print cartridge was successfully restored to operating condition.

• If dots are missing toward the end of the printout, removing dried ink did not restore print cartridge operation. Replace the print cartridge.

4.4.4 Print Cartridges

The Graphic Print Bar graphics print bar uses consumer replaceable print cartridges.

Warning : Print cartridge ink contains chemical substances, which may be harmful if swallowed. Keep new

and used cartridges out of reach of children.

Caution : Do not use refilled print cartridges. Attempting to refill a print cartridge can cause a sudden drainage

and/or leakage of ink, which can damage the product and possibly personal property.

4.4.4.1 Print Cartridge Care

1. Keep unused print cartridges sealed in their original packaging. When replacing a print cartridge, install the new cartridge promptly.

2. Do not turn the product off with the print cartridge out of the service station (left end of the carriage path). The service station cap seals the print cartridge nozzles from exposure to air , to minimize the formation of dried ink in the nozzles.

3. Do not allow the print cartridge contacts and nozzles to touch any surface or object, including your fingers. Skin oil and dust can cause print quality or missing dots problems.

4. Store print cartridges at room temperature.

4.4.4.2 Print Cartridge Expiration

Using print cartridges that are past their expiration date can cause print quality problems. The print cartridge life specification is shown in the following table:

The open life specification of the cartridge is valid for use in an office environment, with a printing frequency of at least once a month. To determine if a print cartridge is past its expiration date, read the use before date printed on the box and ensure the print cartridge is sealed in its original packaging. The print cartridge should be installed before the date shown on the package (see Figure 7). The print cartridge expiration date is also printed on the front of the cartridge body.

4.4.4.3 Causes for Short Print Cartridge Life

There are several causes for short print cartridge life, which are discussed in this section.

1. Printed pages containing graphics or dense print have a higher percentage of ink coverage than specified for average print cartridge life when printing in text mode. The percentage of ink coverage on printed pages has a significant impact on the number of pages per print cartridge. Heavy concentrations of ink reduce the number of pages per print cartridge.

2. The print cartridge may be past its expiration date.

3. The printing device may have been turned off with the print cartridge out of the service station and the nozzles uncapped, leaving them exposed to the atmosphere. This could lead to crusted ink on or in the nozzles may lead to a shorter print life (see section 4.4.3.4 for removing crusted ink). This can also cause misdirected nozzles if ink is allowed to harden on the nozzle plate. This is again caused by the product being turned off with the print cartridge out of the service station for a long period of time allowing the nozzle plate to dry out. If the print out has small white lines (caused by either a missing nozzle or a clogged or misdirected nozzle) clean the print head nozzle by scraping the excessive ink of f and then reinstall the cartridge into the product. If the cartridge servicing routine does not clear the clogged nozzles, the cartridge must be replaced.

4. The original print cartridge package may have been opened. Print cartridges have a longer life sealed in their original package. This is usually true if the cartridge is exposed to higher than normal temperatures.

5. The print cartridge may be faulty. However, frequent occurrences of faulty print cartridges may indicate problems with service station mechanism.

6. The service station may be faulty, which can lead to several types of problems including ink crusting, plugging of nozzles, or air forced into the nozzles. If replacing the cap and wiper do not resolve the cartridge problem, replace the entire service station assembly.
