- The Toner from Laser and Photocopiers are based on Thermal plastic resin and metal oxide (iron oxide). The metal oxide gives black color, whilst the Thermoplat (Styrene Acrylate) acts as a binder to hold the pigment particles together. In both Laser Printers and Photocopiers the toner is transferred to the substract which then passes through heated rollers to fuse the toner onto the substracte. The toner for photocopiers (600 dpi and 1200 dpi) Laser printer are all slightly different but basically of the same make up and melt between 100°C - 150°C. The main differences are in the toner particle size and the temperature at which they are fused. The fusing temperatures are all slightly different for comparable models, but are typically: Photocopiers - 120°C 300 to 600 dpi, Laser Printer - 175° C to 185°C 1200 dpi. The time taken to fuse the toner in the above machines, again will vary but is in the order of 0.1 seconds. The copiers and printers are designed around the imaging on paper and coated film which are porous substractes.
Why to bake the plate in asiatech hot fuser?
To always print long run jobs, trouble free from minute scumming and wreaking of image, it is advisable to bake the plate in the hot fuser for proper toner adhesion. We recomended to strictly bake the plate at 165°C for 90 seconds on each side for flaw less printing and perfect color registration. Baking the plate at higher temperature, setting will damage the image dots, thermal stability and ultimately shorten the print length on second side. Due to overheating the sharpness of the printing is also lost. Too much of baking at higher temperature create scum problem.
How to Use?
1) Put the Multi Pin Power Cord into Main Electrcity Point.
2) Keep the temperature knob at 0°C before swithcing on power supply.
3) The Red Indicator will glow the moment power is on.
4) Now turn the Thermostat knob to set 165°C. The green indicator will glow till the set temperature is achieved. The green Indicator lamp will stop glowing on achivement of set temperature.
5) Now Put the imaged plate inside the drawer on teflon coat aluminium plate and bak for maximum temperature setting of 165°C.
6) Punch the plate if required.
7) Mount the plate on machine cylinder and start printing.
