Daily Maintenance and Cleaning Power Up or Power Down the Print Engine

Press . Power up is complete when the LED light turns from amber to solid green. Power down is complete when the LED light turns from solid green to amber. Head Clean

Press and hold for 9 seconds to begin a light head clean. Perform an initial charge if needed per the instructions in the Getting Started Guide. Inspect Spit Tray The spit tray should be cleaned of dried ink regularly. Failure to do so will lead to a buildup of ink that could eventually hit the bottom of the head and cause a head strike. Remove the ink by wiping with a dry cloth. Nozzle Check Perform a nozzle check from the Color Byte Rip Queue as outlined in your Getting Started Guide. Do not begin printing before you are satisfied with the nozzle check.

Empty the Waste Ink Bottle The ink in the bottle should be emptied at the end of each day (or more often if necessary). Direct Color Systems recommends filling an empty solvent resistant container with cat litter or an oil absorbing product (found in most automotive parts stores). At the end of each day, pour the ink into this can and allow it to harden. Dispose of the mixture in accordance with local and city ordinances. Note

The Waste Ink Bottle can be purged without removing the cap and tube by using one of the supplied syringes. Simply insert the needle of the syringe into the breather hole on the Waste Ink Bottle cap to extract the ink.

Dispose of the ink as outlined above and in accordance with local and city ordinances


Weekly Maintenance and Cleaning Reset Waste Ink Pad Counter and Power Cycle Print Engine. In the Color Byte Rip 9.1 Queue click on the Device Properties icon.

Click on Reset Ink Pad Counter. You must immediately restart the

print engine. It cannot be done the following day.

Note

The waste ink pad counter should be reset at least once per week during normal operations. Failure to do so may result in downtime and the need to contact DCS Technical Support for resolution.

Remove Build Up Ink from the Spit Tray Wearing gloves, wipe the inside of the spit tray with a paper towel. Dried ink that is elevated above the edges should be removed as well. It should break off in your gloved hand, but can also be scraped off with a tool if necessary. Dispose of the towel in accordance with local and city ordinances. X- and Y-axis Cleaning and Lubrication Clean and lubricate print station X-axis shafts and rails Due to the additional heat and dryness created by the UV lamp and its fans, it is necessary to clean and lubricate the rails of the printer often. DCS recommends this be done weekly for moderate users. Heavy users (4-8 hours/day, 5-6 days/week) should perform this maintenance daily. Use your discretion and perform this maintenance as needed.

Use a 3-in-1 oil on the rails and UV light track. Use the G-71 grease on the print engine shaft only. Locate a spare syringe and filling needle in your printer accessory kit. Fill the syringe with a small amount of G-71 grease. Use a new syringe and filling needle and label it to avoid mixing the lubricants with any other liquid, ink, or flush. The G-71 grease can be applied with a gloved finger.

Move the print head carriage into position. Press to raise the print engine several inches above the

media table. Press to unlock the print head carriage. When it has stopped moving, manually move it to the center of the shaft.


With a lint-free cloth, polish the print engine shaft clean.

Also remove any build up around the bushings. Do not spray WD-40 on or near the printer. Do not let it come into contact with the UV lamp bracket or rails. Use the cloth to clean the entire shaft from one end to the other. Slide the print head carriage back and forth. Check that no grease or debris is left on the shaft. If there is, repeat the cleaning procedure. Lubricating the Print Engine Shaft Locate a spare syringe and filling needle in your printer accessory kit. Fill the syringe with a small amount of G-71 Grease Apply a drop or two of G-71 grease to the areas indicated. Do not over-lubricate. Using a gloved finger, spread the G-71 grease evenly across the areas indicated.

Using a gloved finger, apply a small amount of G-71 grease outside and ensure it is applied between the felt bushings and spread as evenly as possible. Failure to lubricate between the bushings could result in increased throughput times. Move the carriage from side to side the full length of the shaft to evenly spread the G-71 grease.


Lubricating the UV LED Lamp Track Locate a spare syringe and filling needle in your printer accessory kit. Fill the syringe with a small amount of 3-in-one oil. Do not use WD-40 on the UV Lamp rails. Clean with a lint free cloth or an IPA wipe when needed. Apply 3-in-one oil to both sides (top and bottom) of the UV track moving the UV light back and forth each time 3-in-one oil is applied to reduce the risk of oil running or dripping on the timing belt.

Using a gloved finger, apply a small amount G-71 grease to the underside of the guide rail. Apply in several areas, moving the print engine for access when necessary. Do not grab the UV lamp. It will track with the print head. Move the print head left and right to ensure even distribution of the grease.

Cleaning the UV LED Lamp

Press to raise the print engine to its maximum height.

Press to unlock the print head carriage. When it has stopped moving, manually move it to the center of the shaft. Turn off the printer by the main power switch. Spray a general purpose glass cleaner onto a soft lint-free cloth and wipe the glass covering the UV light. Do not spray cleaner directly onto the lamp. If this does not clean the glass, dried ink will need to be scraped off. Hold the lamp firmly so that it does not move during this process. Use a glass scraper (found in your accessories kit) and gently scrape across the surface until the glass is clear. Wipe the glass again. Visually confirm that the lamp has not moved by checking that it is higher than the print head and that it is parallel to the media table. Also confirm that the reflectors surrounding the glass have not been damaged. Replace if they are bent.


Lubricate Y-axis Rails Using a lint-free cloth, first wipe the Y-axis rails so they are clean of any debris or lubrication. Apply a

drop or two of 3-in-one oil to the media table rails as indicated. Press and to move the table back and forth to spread the oil.

Oil should be applied to the edges only. Do not apply to the screws.

Apply a drop or two.

Apply the oil to the rails near the center

Using the arrow keys, move the table to the opposite end and again, apply oil to the rails near the center.

Move the table back and forth once more to ensure even distribution of the oil.

Clean the Print Head Encoder Strip for the X-axis.

Both sides of the encoder strip used by the print head should be wiped gently with an IPA wipe (included in the cleaning kit) in order to remove any debris that may have fallen on to it during the lubrication process or from ink residue.


Clean the Capping Station Wiper Blade Clean the wiper in the capping station to avoid streaking in your finished images and/or if drops of ink on the bottom of the print head are not being wiped off after a head clean or initial charge.

Press to manually move the print head away from the capping station.

Pull back on the tab as shown below and then flip up the wiper. Do not remove the capping station. The picture is for

demonstration purposes only.

Wearing gloves, wipe the blade clean with an IPA wipe (provided in

your cleaning kit). Inspect the edge of the wiper blade for damage

or irregular shaped dried ink that cannot be removed with cleaning.

If it cannot be removed, the blade must be replaced. Contact DCS

for blade replacement instructions.

Note

Prior to locking, manually move the Print Head Carriage back to the Capping Station. Failure to do so may

result in an error when locked.

Return the blade to its original position. Press again.
