A3/A4 Printer Needs Parts Cleaning (Wanstead E11)

BROTHER DCP-J4110DW A4 /A3 colour printer scanner & copier bought for home-working a few years ago. . It was printing fine until the LCD screen showed up saying “the ink absorber is full”. It can print on A3 paper and also does 2-sided printing. All other functions are in good working order and I hope someone can clean the ink absorber and use it again. Here is how to clean it.
