Wall UV ink
Wall UV Ink: Channels, Use and Storage
The ink setup, CMYK or CMYK + W, is chosen with the machine, and a machine carries up to 7 ink colours depending on its configuration. Ink is reordered channel by channel, following the colours you use most.
CMYK prints the image directly. The white channel lays an underbase for dark walls and glass; on CMYK + W machines, reorder white together with the colours so the underbase stays on the same factory ICC curves as everything printed over it.
3.0 pl droplets, dry on the pass
The LED UV lamp on the carriage cures the ink as it prints, so each pass is dry as the carriage moves on. The cured finish is water- and UV-resistant.Low-ink alarm and white ink stirring
A low-ink alarm warns you before a colour runs out, so you top up between passes and no band is left half printed. On white-ink setups the machine stirs the white so it does not settle in the supply.Steady flow all day
The printhead is heated on the GP200, GP200B and UP200P and held at a constant temperature on the UP200, so ink leaves the nozzles at a steady rate from the first wall to the last.

- Dry and ventilatedNormal room temperature, in a dry, ventilated place.
- Cool, dark, out of lightUV ink cures under light, so it waits somewhere cool and dark.
- Capped, every timeKeep each container closed; cap a bottle the moment a tank is filled.
- Away from fire, heat and acidsKept apart from acids and organic acid compounds.
Handling on site
Work with ventilation, keep sparks, flames and hot objects away, and do not smoke near the ink. Wear gloves when filling tanks. Waste ink drawn out with the suction tools is not reused; dispose of it under your local regulations, as the MSDS describes.- SGS test reportGZHL2303007145OTOur black UV ink, tested against EU RoHS substance limits; the listed substances were not detected.

The papers that get a job signed off
A hotel, a school or a shop fit-out team may ask what is being sprayed onto its walls before it signs the job. Both documents are sent with your ink order on request, and the client's facilities team files them with the job.White ink setups for dark walls and glass are covered on our White Ink Wall Printer page.
Care liquids and coating
Care Liquids for the Printheads and Coating for Smooth Surfaces
The two care liquids keep the nozzles firing between jobs. Both ship with every machine and run down with every stop and every clean, so they go on the same order as your ink, with coating added when you print glass, tile or metal.

Moisturising liquid
Keeps the printheads moist while the machine stands, and is injected after a flush before a longer stop.Used every time the machine standsCleaning liquid
Flushes ink out of the printheads and wets the tissue under the protection cover. The UP200 also cleans its printheads automatically, which suits a machine on one large site for several days.Used every time the machine is cleanedThe printhead setup sets the liquids
The printhead type and the number fitted decide which liquids go on your list and how fast you go through them. A dual-printhead GP200 or UP200P uses the liquids on two printheads at once.Coating for glass, tile, metal and other smooth surfaces

Maintenance
Printhead Care and Machine Checks
Three routines keep the machine printing: the end-of-day care that lets it print the next morning without a cleaning session, the care that depends on how long it stands idle, and a short mechanical check at every new site.
Daily and weekly printhead care
Wipe, cap, cover
- Wipe the printhead face with a wettable tissue, left to right along the printhead, never top to bottom.
- DX10: the electric suction unit fits over the printhead and keeps it moist.
- DX7, I1600, I3200: moisturise by hand, as in the video.
- Refit the cover; switch off printer and computer.
Test before the first wall
- Print the test lines.
- Prime a broken line again with the suction tool until the syringe runs without air.
Longer clean, ink check
- Tissue over the protection cover, drip UV cleaning liquid where it meets each printhead, fasten the cover so the wet tissue rests on the nozzles.
- Change tissue and liquid every 5 to 7 days; run the cleaning video for your printhead.
- Top up every tank from the matching bottle; check every cap is still loose, since a tightened cap stops the ink reaching the printhead.
When the machine stands idle
Between jobs, a machine can stand for days or weeks. The care depends on how long.
1 to 10 days
Keep the printheads moist as in the daily routine, following the moisturising video.11 to 25 days
Flush the ink out with cleaning liquid, then inject moisturising liquid. An engineer can stay online the first time.Longer
Send your series, printhead type and how long it will stand; the engineer gives you the steps.
Back to work: prime with the suction tool and print the test lines before any wall. Travelling between sites while idle: keep the cover on and pack as your manual shows.
Checks at every new site
Wheels and column
Push gently on the column and print unit; look for looseness or shaking at the wheels and column joints. Tighten any loose screw.Rails and belt
Slide the machine the full rail length by hand. Check fixing strips and screws at each joint, and that the belt is tight and still the right way up.Level and distance
Repeat the wall setup from installation Step 7: level rail, column within 5 mm, printhead at 3 mm or less.Cables
Look along the drag chain and at the aviation plugs; pull only on the metal plug body when you unplug for transport.UV lamp
Keep the lamp face clear of cured ink; lift any build-up off carefully with a blade. When prints stay tacky on a clean lamp, see UV lamp replacement.
Something you cannot fix? Photograph it and send it to the engineer. Symptoms, causes and fixes for print problems are on our Wall Printer Troubleshooting page.
Along the ink path
Ink Dampers, Ink Tubes and Suction Tools
Ink runs from the tanks through the tubes and the dampers to the printheads, and a suction tool draws it through after any change. Dampers, tubes and both suction tools ship with every machine and are supplied afterwards as replacement parts.
Ink tanks
One tank per colour on the carriage. Its cap stays loose while printing.Ink tubes

Suction caps and pads
Supplied as parts. Send a photo of the one you use, and it is matched.Changing a damper or a tube
- Close the tank cap for that colourAs the manual does before the print unit comes off, so ink does not run out of the open line.
- Gloves on, paper towel under the joint
- Change the damper or tube for the same colour
- Loosen the tank cap againWith the cap tightened, ink cannot flow to the printhead.
- Prime with the suction toolUntil the syringe draws ink without air.
- Print the test linesA complete set of lines for that colour confirms the change.

Checking that it is the damper, and not air in the tubes or a tight tank cap, is covered on our Wall Printer Troubleshooting page.
The main wear part
Replacement Printheads and the Fitting Steps
Same type as fitted. A replacement printhead is the same type your machine was built with, so the software settings, the colour curves and the test pattern stay the same. It is due when its test lines stay broken after priming and cleaning, or after damage; send a photo of the test pattern first and an engineer confirms it with you before you order.

Nozzles per printhead, and what follows from it
Faster, longer life, fewer clogsShorter life, less tolerant of cleaning
On a DX10 machine under heavy weekly work, printheads are replaced more often than on an I1600 machine, so a spare DX10 on the shelf keeps a job moving.


What to tell us
- The series and the printhead type.
- On dual-printhead machines: one printhead or both.
- On CMYK + W machines: the colour printhead or the white one.
- A photo of the label on the old printhead settles any doubt.
- Have the printhead on the benchOrdered to your series and printhead setup, before you start.
- Watch the video onceFor your printhead type, before touching the machine.
- Switch off and photograph the cablesWhere the ribbon cables enter the old printhead, so their order and orientation are on record.
- Swap the printheadRemove the old one as the video shows; fit the new one in the same position.
- Ribbon cables: same order, same way roundMatch your photo. A cable in the wrong slot or turned over stops the printhead from firing correctly.The step MAXWAVE marks for attention
- Prime until ink runs without airWith the suction tool.
- Print the test linesEvery line in the pattern for your printhead type should be complete.
- CMYK + W: print the calibration patternCheck that colour and white overlap.
- Send the photos on WhatsAppTest lines and fitted cables. The engineer checks them with you and stays on the thread while you print the first wall.

Choosing a printhead setup for a new machine is covered on our Wall Printers page; if colour and white do not line up after a change, the alignment settings are on our Wall Printer Troubleshooting page.
Wear parts
UV Lamp, Wheels, Belts and Data Cables
These parts wear with hours of curing, travel along the rails and knocks between sites. After replacing any of them, print the test lines and a short test on the wall, then send a photo and a clip of the carriage running to the engineer.

UV lamp: replaced when curing power falls
The lamp's power falls with long use, and when it falls far enough the ink no longer cures fully as the carriage passes.
- Check 1
Lamp face clean?
Cured ink built up on the face blocks the light. - Check 2
Brightness turned up?
The knob on the back of the lamp may be set too low. - Still tacky
The lamp is due
Clean face, brightness up, prints still tacky: it has reached the end of its power.
Order
Matched to your series. Send the series and a photo of the lamp on the carriage, with any label on it. A spare lamp can go on the same order as your ink.Fit
Switch off and let the lamp cool. Disconnect it, remove it from its mount, fit the new lamp in the same position and reconnect. An engineer guides the mount for your series by WhatsApp photos or video.Confirm
Set the knob, print a test patch and touch its edge once the carriage has passed: dry to the touch. Send a photo of the patch and the knob setting.

Wheels, black and white
Replaced when worn flat, cracked or loose; a loose wheel shows in the print as lost sharpness. Send the series, wheels or rails, and a photo of the wheel. The GP200 runs its print unit on a guide rail and sliders instead of plastic wheels, which keeps its noise and wheel use down.Belts
Replaced when the teeth wear, the edge frays or it no longer holds tension.- GP200B and UP200P floor rails: clamped at each end, through the belt gear as the manual shows.
- Slide the print unit along its full travel by hand: smooth, no slack.

Data cables
Fixed at both ends of the drag chain so they cannot move while printing. Order with the series and a photo of both ends.
Casters on the base
Rail bases carry their own casters and fixings. A photo of yours settles which.
Wheels or rails: the base decides
With the series, the base sets the wheels and the belt on your list.Tacky prints, looseness and shaking at the wheels are diagnosed on our Wall Printer Troubleshooting page.
