The HP Color LaserJet CM6040 printer contains four imaging drums that correspond to each of the colour toner cartridges: black, cyan, magenta and yellow. Each drum is designed to print approximately 35,000 pages at an estimated 5 per cent coverage. The drums have a considerably longer life than toner cartridges but still need to be replaced regularly to maintain optimal print quality on your documents and photos. The LaserJet CM6040 keeps track of the number of prints and it will alert the user when it's time to replace the drum.

Things you need
- One each of the following imaging drums:
- CB384A black
- CB385A cyan
- CB386A yellow
- CB387A magenta
Lay a few sheets of paper on the floor or on a nearby table. Put the used drums on the paper as you remove them to avoid getting toner residue on the floor or other surfaces.
Grasp the front cover of the printer at the top right and top left corners and gently pull the cover down.
Grasp the end of the drum and pull it straight out toward you. Use your other hand to help support the opposite end of the drum as you pull it free from the printer. Place the drum on the sheets of paper that you have prepared.
Remove the replacement drum from its box and protective cover.
Align the replacement drum with the appropriate slot in the printer, according to the colour you are replacing. Gently slide it forward into the printer until you feel and hear it snap into place. The grey-coloured drum cover will slide off of the drum and remain on the outside of the printer. Discard the drum cover.
Put the used drum into the protective bag that held the new drum and then put the bag into the drum box. Dispose of it according to the instructions contained in the box or according to your local regulations. Discard the sheets of paper on your floor or table.
Repeat the above procedure for each imaging drum that you need to replace.
Shut the front cover of the printer. The printer will recognise the new drum and will recalibrate and re-initialise. When the display reads "Ready," the printer is ready to print.
Tips and warnings
- The printer will warn you that the drum is getting low and prompt you to order a replacement when approximately 15 per cent of its useful life remains.
- The printer display will show "Replace Drum" when the drum has exhausted its life. Continue using the drum until the printer prompts you to replace it.
- Avoid spilling loose toner on your carpet or other surfaces.
