If the site of bleeding is not identified angiographically, empirical embolization can still be effective. For instance, the LGA can be embolized if the bleed is in the fundus of the stomach or distal esophagus. Engaging the LGA may require a Waltman loop, a left gastric catheter, or a microcatheter.
Toner is a largely powder-based printing agent used by laser printers, using organic compounds and polymers to make up the majority of the material. Pros. #1: Toner means faster printing. Toner cartridges and laser printers on the whole operate more quickly than their ink-based cousins. This is largely due to the precision that s possible with a laser over a spray of ink. Each must travel across the paper and either etch a pattern (laser) or apply ink (ink), but a laser is far more precise than even microscopic droplets of ink can be.
3. Fuser. The fuser is the part of the printer that bonds toner to the paper through heat and pressure. Fusers DO NOT have a built in supply of toner, they only bond toner that is already on the paper. Therefore fusers can not cause light print, unless the toner is sticking to the fuserâs upper roller.
