VJ628 Preventative Maintenance

  • Updated

 

Do you want to make sure that you are taking the right steps to keep your VJ628 healthy?

Look no further!

This article will tell you all about our recommended best practices:

 

Inspection, Cleaning, and Part Replacement Checklist 

  • It is imperative to routinely inspect the printer and replace any consumable parts as soon as possible. 
  • We highly recommend maintaining a maintenance log that is kept near the printer to keep track of the life spans of the various consumable parts and when the parts require changing.
  • If you are a business running multiple shifts with the Sawgrass VJ628, a daily cleaning log/sign off sheet is strongly suggested to maintain the printer and employee accountability. 

 

Consumable Parts Replacement Log 

  • The following checklist has been designed by Sawgrass to use after each production run.  It includes any preventative maintenance processes that need to be performed on the VJ628. 
  • If you use the printer for more than 8 hours per day, be sure to log and repeat the steps in the form below every 8 hours. 

 

Optimal Environmental Conditions 

  • Be sure to maintain the printer in an environment following the guidelines below:
     
  • Multiple Shifts: Keep track of the environmental conditions where the printer is kept by logging the temperature and humidity of each shift to maintain the machine accordingly. 

 

Nozzle Check 

  • Perform a nozzle check at the beginning of each production cycle and large job queues. 
  • It is not advised to print when there are missing nozzles.  Perform a short, normal, or long clean depending on how many nozzles are missing. 

 

Little Charge 

  • In rare cases where nozzles are not recovered by using either the short, normal, or long clean processes, or if air bubbles are present in the ink lines, it is suggested to perform a Little Charge which should be followed by a normal clean. 
     
  • The Little Charge Procedure uses a large amount of ink and is to be used to flush the ink lines and print head.  This should not be used as a standard cleaning procedure. 

 

Monitor Ink Levels 

  • Check the ink levels at the beginning of each production cycle and as needed in between. 
  • The ink levels can be viewed in the ValueJet Status Monitor.  You can use this information to plan and predict for when you will need to replace the cartridge/s. 
  • The ValueJet Status Monitor updates the ink levels when the Printer Info button is selected. 
  • Select the “Auto Printer Information” tool in the printer status window of the ValueJet Status Monitor.  From here, you can select the refresh rate for the printer information.  Intervals of 3, 10, 30, or 60 seconds between ink level updates can be selected from here. 

 

Monitor Waste Levels 

  • It is best to check the level for the waste ink at the beginning of each production cycle.  
  • Select “Reset Waste Ink” button when the physical waste tank has been emptied to prevent the waste ink from overflowing into the printer. 
    • The container will need to be at least 1.4 Liters. 

 

Check Status Information Screen 

  • It is recommended to check the Status Information Screen in the ValueJet Status Monitor at the beginning of each production cycle and as needed for any alerts, error messages, or if the printer begins to beep. 

 

Printer and Paper Alignment 

  • And Alignment check should be performed every time the media/paper roll is changed, the printer is moved, or if there is blurry image output. 
  • Alignments are necessary to avoid poor output like ghosting or image blur.   

 

Advance Settings Tab / Auto-Clean Settings 

  • Multiple Shift Users: Confirm your settings have not been changed once a month. 
  • Auto-Clean settings should be set to at least 1 short clean every 6 hours (360 minutes). 
    To confirm this, select the Advanced Setting tab in the Remote Panel of the ValueJet Status Monitor, adjust if needed and select Update in the top of the screen to save the setting.
     
     

Advance Settings Tab / Spitting Function 

  • The printer will “spit” into the flushing pad before each nozzle check and before printing starts.  You may also trigger this manually using the Advanced Settings Tab in the ValueJet Status Monitor.
  • When using Sawgrass inks, you can set the spitting Pass Count to 25 and Update. The print head will make 25 passes before returning to the flushing box to spit, as a maximum limit without causing any long-term effects to the equipment. 
  • If there is more nozzle loss with this adjustment, set the Pass Count to lower than 25 until you find the appropriate setting for your environment. 

 

Platen Front Surface Cleaning 

  • Wipe down the platen weekly or if excessively dusty/dirty 
  • Be sure to keep the platen clear of any dust, debris, or ink spillage. 
  • DO NOT wipe any dust/debris towards the direction of the print head.   

 

Horizontal Encoder Strip / Encoder Wheel Cleaning 

  • Clean the Horizontal Encoder Strip and Encoder wheel monthly, unless there is excessive dust/debris build-up 
  • Use a lint free cloth and Sawgrass Clean 60 cleaning solution.
  • DO NOT wipe any dust/debris towards the direction of the encoders.   

 

Clean Flushing Box Sponge “Flushing Pad” 

  • Clean the Flushing Box/Pad weekly unless needed. 
  • For best results, clean the Flushing Box/Pad with hot distilled water and Sawgrass Clean 60 cleaning solution. 
  • Keep area free of as much debris and waste ink accumulation as possible. 
  • Single Shift: Replace every 2 months. 
    Multiple Shifts: Replace every 480 hours of use. 

Clean the Print Head Circumference 

  • Clean the Print Head Circumference weekly unless needed. 
  • For best results, clean the area with hot distilled water and Sawgrass Clean 60 cleaning solution. 
  • Keep area free of as much debris and waste ink accumulation as possible. 
  • Use foam tipped cleaning swabs. 
  • Never use alcohol or eco-solvent cleaners on or around the print head. Serious damage can occur. 
  • NEVER directly touch the print head with swabs or fingers 
  • Never use cotton tipped swabs since they leave behind fibers/lint 

Clean the Capping Area 

  • Clean the Capping Area weekly unless needed. 
  • For best results, clean the area with hot distilled water and Sawgrass Clean 60 cleaning solution. 
  • Keep area free of as much debris and waste ink accumulation as possible. 
  • Never use alcohol or eco-solvent cleaners on or around the print head. Serious damage can occur. 
  • Single Shift: Replace every year. 
    Multiple Shifts: Replace every 2880 hours of use. 

Clean the Wiper Blade 

  • Clean the Wiper Blade weekly unless needed. 
  • For best results, clean the area with hot distilled water and Sawgrass Clean 60 cleaning solution. 
  • Keep area free of as much debris and waste ink accumulation as possible. 
  • Use foam tipped cleaning swabs. 
  • Never use alcohol or eco-solvent cleaners on or around the print head. Serious damage can occur. 
  • Single Shift: Replace every year. 
    Multiple Shifts: Replace every 2880 hours of use.
     

Clean and Grease the Y-Axis Rail 

 

  • Use VJ628 Y-Rail Grease 
  • Single 8-hour Shift Users: Clean and Apply grease every 6 months or as needed. 
    Multiple 8-hour Shift Users: Clean and Apply Grease every 1440 hours or as needed. 
  • Keep area free of as much debris and waste ink accumulation as possible. 
  • Be sure to not wipe dust/debris towards the print head. 

 

Inspect / Replace Cutter Blade 

  • Inspect paper for jagged edges, blade wear, or if paper dust collects around cutting areas and capping station. 
  • Single Shift Users: Inspect paper cutting edge and blade for wear every 6 months. 
    Multiple Shift Users: Inspect paper cutting edge and blade for wear every 1440 hours.

 

Inspect Media Holders 

  • Inspect the Media Holders daily for bent edges, abnormal wear, or if ink and paper dust is collecting underneath. 
  • Slide the Media Holders back and forth to free up debris under the holders. 
  • DO NOT use the printer if the Media Holders are bent.  This can cause a headstrike.
