Maintenance is important for the long life of any machine and your Sawgrass Printer is no different.
This guide will walk you through several important maintenance and troubleshooting steps to help along the way:
Some quick important notes:
- Not performing maintenance regularly can lead to damaged and/or worn parts, eventually creating more sever issues, and possibly even making the machine unusable
- The printer does some of its own maintenance. It performs a cycle every 10 hours. During this cycle, the head and nozzles are cleaned to help reduce the chance of print head failure or clogged nozzles
- Because of this it's very important to leave your printer plugged in and turned on at all times
We're going to cover:
The Nozzle Check will show you if you have any nozzles that are clogged or damaged. It is recommended to print a nozzle check periodically or if the printer has not been used/powered on. Blocked nozzles appear as missing dashes/lines on the nozzle check print out. Please refer to the troubleshooting tips below if you print a nozzle check and you have missing nozzles.
If you perform a Nozzle Check and see that there are missing nozzles, we recommend the following steps to recover them:
- No more than 3 head cleans, each followed by a nozzle check
- No more than 1 head flushes, each followed by a nozzle check
- If the nozzle check is still not satisfactory with limited improvement, then the next step is cleaning the capping station with some hot distilled water. (Do not use anything besides warm/hot distilled water. This can cause damage to the capping station sponge and print head.). We would recommend cleaning the sponge in the capping station until the water drains quickly from the capping cup. As a result, you may need to clean the capping station multiple times. Once the capping station filter is clean, perform a head flush followed by a nozzle check
- Perform an ink charge as a last resort. Please be advised that this will use 20% of the ink cartridge.
Tip: To reduce unnecessary ink consumption, it is recommended to perform the head clean or head flush on the relevant head, this will either be Head 1 (Cyan/Black) or Head 2 (Magenta/Yellow).
A Head Cleaning will usually clear any blocked or clogged nozzles. This process does consume ink but is sometimes necessary to clear the clogged nozzle(s).
- Perform a head cleaning up to 3 times to clear missing nozzles.
- Print and check for any changes in the nozzle check test pattern between each head.
- Do not turn the printer off during print head cleaning. If the printer is turned off during a print head cleaning, start again by printing a nozzle check test
A Head Flush is only suggested to be used if the Nozzle Check is not satisfactory after 3 Head Cleanings. This process uses a higher amount of ink and extensive flushing can damage the Print Head.
Follow the steps to perform a Head Flush on the menu of the printer.
Below are some things to keep in mind:
- Perform a head flush only if print head nozzles cannot be cleared by up to 3 head cleanings.
- Head Flushing consumes more ink than Head Cleaning
- Do not perform more than 1 Head Flush
- If nozzles are still missing after 3 Head Cleanings and 1 Head Flush, contact Sawgrass Tech Support for further assistance.
Important: Do not power off the printer during the Head Flush or Head Cleaning process. If the printer loses power, power it on and repeat the cleaning process beginning with the Nozzle Check.
The capping station is located under the print head and its function is to prevent the ink on the print head from drying out. A dirty capping station may cause one of the following:
- Missing nozzles
- Banding in certain colors
- Service code errors
Horizontal banding that is present in one or more colors and presents as thick dark or light bands can indicate that you have a dirty capping station. To clean the capping station, we recommend that you pour a small amount of hot distilled water into the suction cup and let it soak for 5-10 minutes. Once the sponge inside the suction cup is clean, the water will drain to the waste tank.
Horizontal lines or banding can be caused by one or more of the following:
Horizontal Banding can be caused by not using the correct print settings. To ensure that your print quality is best, it is recommended to use Sawgrass Print Manager.
Paper feed adjustments
Horizontal Banding can be caused by the paper feed adjustment not being set properly. The paper will not advance the correct distance which can cause a banding effect on your prints. To ensure that the Paper Feed is set correctly, perform a Paper Feed Adjustment. This is a simple adjustment that can be access through the printer menu > Printer Features> List/test Print > Adjust Paper Feed.
The most common causes of Vertical Banding are:
- Incorrect print head position adjustments
- Dirty or damaged horizontal encoder
You can try these methods below to resolve this issue:
- Perform print head position adjustment.
- If the issue is only in the cyan channel, please try printing in Advance Photo.
- Clean the horizontal encoder/Check encoder for damage.
The printer adjustments are separated into three parts:
- Paper Feed
- Head Position
These adjustments control the positioning and feeding of the paper. If the adjustments are incorrect this can result in one or more of the following:
- Skewed Prints
- Double printing
- Streaks or Patches on Images
- Banding (White horizontal lines evenly down the page)
A paper misfeed is commonly caused by the following:
- Incorrect settings/Size Mismatch
- Sensor error
- Paper Jam
Incorrect settings/Size Mismatch
If an incorrect paper size is selected in the settings, the printer will detect a paper size mismatch and will display a paper misfeed message on the LCD display. This can usually be cleared by pressing the Job Reset button or Form Feed button on the front panel of the printer.
If you have confirmed that the print settings are correct, the paper misfeed message could be caused by a sensor error. In most circumstances this is caused by a sensor, or the paper feed rollers being dirty and requires cleaning.
Another cause of a paper misfeed is a page being caught by the print head as the page is being printed. This should only become a concern when there is a consistent problem with paper jamming in the printer. This could indicate a mechanical issue/damaged part. If the paper misfeed error continues or is permanently displayed, you can obtain the Jam codes for our support team to investigate the error further.
