UV Inkjet Lamp Life And Maintenance
In this economy, savvy companies are trying to stretch cash outlay and bolster their bottom line. They have chosen UV inkjet printers for low volume and prototype work because of the considerable savings in terms of prepress time and substrate waste.
Inkjet printers use one or two UV systems depending on machine design. Each system has these common components.
Inkjet lamp housing maintenance
Taking care of your printer’s curing system is an easy way to reduce machine costs. Most inkjet UV lamps are air cooled hence they must live with whatever air is provided.
Lamps must be kept clean, free of dust, powder, grease, smoke and misting ink. Often, shop contaminants will blow over the lamp sticking to the quartz literally baking onto the surface. This reduces UV energy and may cause bulb overheating.
Bulbs and reflectors require inspection every 150 hours of operation. If lamp has external contamination or reflector surface is dull, clean immediately! Use a lint free cloth with Windex or Simple Green to clean. Do not waste your money on special UV lamp
cleaners as they have dubious value!If solvents are permitted, use isopropyl alcohol.For extreme cases, use a mild abrasive such as Soft Scrub to clean the UV lamp. Be sure to rinse any residue off the glass and allow to dry before reinstalling lamp.
The same cleaning schedule applies to the quartz plate utilized in many systems. To maximize curing efficiency, keep your system clean. TCS Technologies offers replacement quartz plates at a fraction of the OEM component.
Most inkjet manufacturers have their own proprietary curing system design. The hope is to maintain replacement parts business. This does not mean every quartz plate, filter or replacement UV lamp is only available from the OEM. Search the internet; you will discover companies offering alternative components at a discount.
Most lamp housings incorporate one or two cooling fans to maintain bulb temperature. Most have a filter screen to prevent dust and dirt from being blown onto the UV bulb. Regularly clean the filter to maintain cooling efficiency. The higher the bulb power, the more heat created. Most lamp assemblies have a thermal safety switch. This shuts off the UV lamp in case of excess temperature. Clean the screen or replace it regularly. Environmental factors (shop-air, etc.) can accelerate filter clogging.
Some printers use an all-in-one cassette system containing both the lamp and reflector. The only way to purchase a new lamp from the OEM is replace the entire assembly. Rather than replace the entire cassette, TCS Technologies will clean your existing cassette and install a new UV lamp for a cost savings 60% or more. We polish the reflector, remove any ink or dust deposits, recycle your old lamp and install a brand new TCS Technologies UV lamp. Typical turnaround at our facility is one day. This minimizes downtime while maximizing savings.
Maintaining your UV inkjet assembly it not complicated or time consuming. The rewards are immediate and benefits long lasting.
