If you have some mechanical skills and a steady hand you can change the drum. However it worth the money to pay a "pro"to do it. Also you may want to replace the cleaning blade too.
1. Open the front cover - where the toner is. 2. Remove the black cover - 2 screws 3. Remove a little stopper at the bottom of the drum unit + 1 screw 4. Disconnect the drum unit cable. 5. Take off 2 screws which secure the Drum Unit. 6. On top of the Drum unit you should see 2 white plastic stoppers - front and back side ends - You have to push them inside to keep the cleanng blade away from the drum. 7. Remove the MCH assembley - 1 screw. 8. Remove the front separation claws + plate - 2 screws. 9. Remove the Drum Shaft 10. Replace the Drum
There are few details about how to manipulate a Drum - Do not touch the surface, do not expose it to intense light...

Re: Kyocera 1810 drum replacement
First, what kind of technical background do you have? Also when replacing the drum you should replace the drum blade. Most of the drum/blade kits do not come with padding powder anymore so you will need the padding powder also -- if you do not use the padding powder you will get drum blade jitter and trash the brand new drum!!!!
TO replace the drum you will need to remove the toner cart., 1-2 covers, the dev. unit (developer) and then the drum unit. You will then have to take the drum unit apart to remove the old drum and blade. *****NOTE***** DO NOT TOUCH THE DRUM SURFACE OR THE MYLAR (RUBBER PART) OF THE BLADE WITH YOUR SKIN!!!!!! The oil from your skin will damage the drum and could damage the blade, again -- then they would be trashed.
I would spend the money to have a trainer tech. come out and replace/ rebuild your photo conductive unit for you. It would be money well spent.

for most copier those black streaks are caused by poor cleaning of the Photo Conductor Drum these can be fix by replacing the cleaning blade. after replacing them clean the Photo Conductor Unit and make some test copies.
there are two parts to the copy of this machine, one is the photo conductor (drum, green cylinder ***'y) and the toner which fits in the drum ***'y.
you replaced the drum but you need to replace the toner as well (low toner)

Hi there the following is the description from the service manual hope this helps you Thanks J
441 PCU (CMY) motor error The drive motor of the CMY PCU is not locked. • Defective gear • Voltage between pins 2 and 14 (CN12 on engine control board) abnormal (not +24V), or pin 12 (CN12 on engine control board) unable to send motor clock • Defective CMY PCU drive motor 1. Replace the CMY PCU. 2. Replace the engine control board. 3. Replace the main drive unit assembly.
I would try replacing the CMY PCU (Drums (Photo Conductor Units) first before any of the others.
the vertical line that you saw is an indication of either it is normally worn out, or something has caused the scratched, by any material ( PC drum is very sensitive to any material and can easily damaged or scratched any solid and unwanted dirt inside) see you actual meter reading. if it falls on the first thousand copies or print then it might have caused by a scratched, if it falls beyond the PM parts repalcement then there is nothing you can do but to replace this.
sometimes you can swap the colors, by the affected color use the yellow drum unit to the affected drum, the vertical would not that be obvious.
